No network protocol handler is involved.\nAC:L - The attacker drives both sides of the race \u2014 a multi-threaded write() loop dirties the inode while the attacker forces cgroup writeback switches by dirtying the file from a second memcg and tearing that cgroup down, making the old wb\u0027s last reference drop. Attempts are unlimited and the bug was observed occurring spontaneously during normal boot, and CONFIG_CGROUP_WRITEBACK is default-y on all mainstream kernels.\nPR:L - Only an unprivileged local account with write access to a file on a writeback-capable filesystem (ext4/xfs home or /tmp) is needed; cgroup manipulation used to widen the race is available to ordinary users through systemd\u0027s delegated per-user cgroup subtree.\nUI:N - The attacker triggers everything itself through its own write() syscalls and cgroup activity; no victim action or interaction is required.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The freed bdi_writeback is dereferenced as `wb-\u003ebdi-\u003ecapabilities`, so a re-sprayed object yields an attacker-controlled pointer dereference and an arbitrary kernel-memory read primitive, enabling disclosure of arbitrary kernel data.\nI:H - wb_wakeup_delayed() writes into the freed object (spin_lock_irq on wb-\u003ework_lock) and inserts the freed `wb-\u003edwork` timer into the timer wheel, giving list-write primitives and an attacker-controlled `timer-\u003efunction` \u2014 a direct control-flow hijack path to arbitrary kernel code execution.\nA:H - The use-after-free reliably produces a kernel oops/panic as reported in the original crash trace (__mark_inode_dirty+0x124), and can be triggered repeatedly to crash the system."

Per kernel guidance, WiFi frame injection is Adjacent.\nAC:L - The attacker controls every precondition: SSID hiding, BSSID, the two channels, the beacon/probe-response pairs that build the hidden groups, and the CSA that fires `cfg80211_update_assoc_bss_entry()`; the victim\u0027s routine background scans supply the rest without attacker effort. The freed object\u0027s size is attacker-chosen via IE length, so heap grooming is also under attacker control.\nPR:N - No credentials or account on the target system are needed; beacons, probe responses and public action frames are unauthenticated and unprotected (beacon protection/BIGTK is rarely deployed), so a rogue AP or frame injector reaches the code with zero privileges.\nUI:N - Scanning, beacon processing and CSA handling are performed automatically by the kernel for an associated STA \u2014 no user action is required, and the attacker can spoof the legitimate AP\u0027s frames against an already-connected victim.\nS:U - The freed `cfg80211_bss_ies` allocation and all corrupted state live in the kernel\u0027s own slab and cfg80211 BSS list; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The stale `beacon_ies`/`ies` pointers are read by `cmp_bss()` and, critically, copied wholesale to userspace via `NL80211_BSS_BEACON_IES` in scan dumps, disclosing reallocated freed heap contents \u2014 and an attacker-controlled `len` after reallocation extends this to a large out-of-bounds kernel memory read.\nI:H - The shared IEs are freed while still owned by the beacon BSS, so the later `bss_free()` performs a second `kfree_rcu()` on the same object \u2014 a double free of an attacker-sized allocation, a well-established primitive for arbitrary write and control-flow hijack; freed-memory contents also drive rb-tree ordering decisions.\nA:H - Use-after-free reads in `cmp_bss()` plus the subsequent double free corrupt the slab allocator and reliably produce oopses/panics, and the condition can be re-triggered at will by an in-range attacker."

Title
Bluetooth: Fix use-after-free in l2cap_sock_cleanup_listen()
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix use-after-free in l2cap_sock_cleanup_listen()
syzbot reported the splat below without a repro.
In the splat, a single thread calling bt_accept_dequeue() freed sk
and touched it after that.
The root cause would be the racy l2cap_sock_cleanup_listen() call
added by the cited commit.
bt_accept_dequeue() is called under lock_sock() except for
l2cap_sock_release().
Two threads could see the same socket during the list iteration
in bt_accept_dequeue():
CPU1 CPU2 (close())
---- ----
sock_hold(sk) sock_hold(sk);
lock_sock(sk) <-- block close()
sock_put(sk)
bt_accept_unlink(sk)
sock_put(sk) <-- refcnt by bt_accept_enqueue()
release_sock(sk)
lock_sock(sk)
sock_put(sk)
bt_accept_unlink(sk)
sock_put(sk) <-- last refcnt
bt_accept_unlink(sk) <-- UAF
Depending on the timing, the other thread could show up in the
"Freed by task" part.
Let's call l2cap_sock_cleanup_listen() under lock_sock() in
l2cap_sock_release().

"value": "AV:A - The vulnerability lives in the Bluetooth L2CAP socket layer, and the objects that get freed and reused are child sockets that only ever exist because an adjacent Bluetooth peer established L2CAP connections to the listening PSM (`l2cap_connect_cfm` \u2192 `l2cap_sock_new_connection_cb`). The attack surface therefore spans the Bluetooth piconet/radio range.\nAC:L - The attacker controls both sides of the race \u2014 one thread blocked in `accept()` on the listening L2CAP socket and another calling `close()` on the same fd \u2014 and can retry indefinitely while keeping many pending children queued to widen the `bt_accept_dequeue()` iteration window. Nothing about the race depends on conditions outside the attacker\u0027s influence.\nPR:L - `l2cap_sock_create()` requires no capability for `SOCK_SEQPACKET`/`SOCK_STREAM` (only `SOCK_RAW` gates on `CAP_NET_RAW`), and binding a dynamic PSM \u2265 0x1001 bypasses the `CAP_NET_BIND_SERVICE` check, so an ordinary unprivileged local user can create, listen on, accept from and close the socket that triggers the race.\nUI:N - The race is driven entirely by the attacker\u0027s own threads performing `accept()` and `close()` syscalls plus inbound L2CAP connections; no victim action is needed.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The freed `struct sock` is read after free (`debug_spin_lock_before`/`release_sock`) and lives in a general kmalloc cache, so an attacker who sprays replacement objects into the freed slot can read back attacker-chosen or sensitive kernel data through the stale socket, giving an arbitrary-read path.\nI:H - After the free the kernel still writes into the object \u2014 `list_del_init()` on the freed `accept_q` node (an unlink write of attacker-groomable pointers), `sk_acceptq_removed()`, a refcount decrement, and spinlock stores \u2014 yielding a write primitive into reclaimed heap memory that is exploitable for control-flow hijack and privilege escalation.\nA:H - The bug is a confirmed slab use-after-free (syzbot KASAN splat) that corrupts the parent\u0027s accept queue list and takes a spinlock on freed memory, reliably producing an oops/panic and unbootable-level kernel instability."

There are no capability checks anywhere in net/smc along this path.\nUI:N - The server-side handshake worker processes the attacker\u0027s connection automatically with no action by any local user or administrator.\nS:U - The fault and its consequences are confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The fault is a read of NULL+0x2ec (page fault error code 0000) that aborts immediately; no data is returned to the attacker and no out-of-bounds memory is disclosed.\nI:N - No memory is written and no attacker-controlled data corrupts kernel state \u2014 the dereference faults before dma_need_sync() can act.\nA:H - The NULL dereference oopses the smc_hs_wq kworker, killing it while it holds smc_server_lgr_pending and the socket lock, so the SMC subsystem deadlocks permanently for every later connection; with panic_on_oops the whole system panics, and the attacker can repeat it unauthenticated at will."

Title
wifi: cfg80211: sme: cap SSID length in __cfg80211_connect_result()
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: sme: cap SSID length in __cfg80211_connect_result()
If the ssid->datalen is more than IEEE80211_MAX_SSID_LEN (32) it would
lead to memory corruption so add some bounds checking.

This is the standard WiFi frame-injection adjacent-network vector.\nAC:L - The attacker fully controls every precondition \u2014 the rogue AP\u0027s per-link beacon contents, the SSID element length (up to 255), the link IDs, and which link is used for association \u2014 and can force (re)association with deauthentication frames. No condition lies outside the attacker\u0027s control.\nPR:N - No credentials or account on the victim system are required; the code runs during association processing on the client, triggered purely by frames the attacker transmits. An open/evil-twin AP suffices.\nUI:N - Association and roaming are performed automatically by the WiFi stack for remembered and open networks, and an attacker can force reassociation with deauth frames, so no deliberate victim action is needed.\nS:U - The corruption is confined to kernel heap memory belonging to the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `wdev-\u003eu.client.ssid_len` is set to the full unclamped datalen, so `nl80211.c:4530` copies up to 223 bytes of adjacent kernel heap out to userspace via NL80211_ATTR_SSID, and the write primitive over BSS pointers enables broader disclosure.\nI:H - An out-of-bounds write of up to 223 fully attacker-controlled bytes overwrites `wdev-\u003elinks[]`, including `client.current_bss` pointers that are later dereferenced and refcount-decremented, yielding a controlled-pointer primitive suitable for control-flow hijacking.\nA:H - Corrupting the `wdev-\u003elinks[]` BSS pointers and surrounding `ieee80211_sub_if_data` state leads to bogus pointer dereferences in `cfg80211_wdev_release_bsses()` and kernel panic; heap overflow reliably crashes the system."

Title
ax25: properly unshare skbs in ax25_kiss_rcv()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ax25: properly unshare skbs in ax25_kiss_rcv()
Bernard Pidoux reported a regression apparently caused by commit
c353e8983e0d ("net: introduce per netns packet chains").
skb->dev becomes NULL and we crash in __netif_receive_skb_core().
Before above commit, different kind of bugs or corruptions could happen
without a major crash.
But the root cause is that ax25_kiss_rcv() can queue/mangle input skb
without checking if this skb is shared or not.
Many thanks to Bernard Pidoux for his help, diagnosis and tests.
We had a similar issue years ago fixed with commit 7aaed57c5c28
("phonet: properly unshare skbs in phonet_rcv()").

AX.25 frames are not IP-routable in-kernel, matching the AV:A precedent set for the sibling netrom frame-receive CVE-2026-23098.\nAC:L - Every received AX.25 frame reaches the unshared-skb path; no crafting, timing window, or memory-layout grooming is required of the attacker, who fully controls frame content and rate. The only precondition \u2014 an AF_PACKET tap on ETH_P_AX25 placed after ptype_base \u2014 is the standard axlisten/mheardd monitoring setup present on ordinary AX.25 stations, which is how the bug was reported in the field.\nPR:N - AX.25 is entirely unauthenticated and ax25_kiss_rcv() runs on every frame before any socket, callsign, or connection state check. An attacker simply transmits on the channel or sends BPQ frames on the LAN with no credentials on the target system.\nUI:N - The frame is processed in softirq context by the receive path as soon as it arrives; no local user or administrator has to open, read, or otherwise interact with anything.\nS:U - The corruption is confined to kernel skb/socket-queue structures within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The shared skb is mutated (skb_pull, header resets, skb-\u003edev/protocol rewrite) and re-queued while another consumer still reads it, so packet-socket consumers receive mis-parsed buffers, and the resulting use-after-free/list corruption of sk_buff objects yields a read primitive over freed kernel memory.\nI:H - Queueing a shared skb simultaneously onto the backlog, an AX.25 socket receive queue, and ax25-\u003efrag_queue produces sk_buff list corruption and double free, and skb_orphan() on a shared skb corrupts another socket\u0027s rmem accounting \u2014 classic heap-corruption primitives leverageable for arbitrary write and control-flow hijack.\nA:H - The reporter reproduced a hard kernel crash from a NULL skb-\u003edev dereference in __netif_receive_skb_core(), and the underlying skb double-queue/double-free reliably panics the machine; the attacker can repeat it with every frame transmitted."

Title
scsi: lpfc: Fix buffer free/clear order in deferred receive path
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix buffer free/clear order in deferred receive path
Fix a use-after-free window by correcting the buffer release sequence in
the deferred receive path. The code freed the RQ buffer first and only
then cleared the context pointer under the lock. Concurrent paths (e.g.,
ABTS and the repost path) also inspect and release the same pointer under
the lock, so the old order could lead to double-free/UAF.
Note that the repost path already uses the correct pattern: detach the
pointer under the lock, then free it after dropping the lock. The
deferred path should do the same.

No privileges on the target host are needed.\nUI:N - The race is triggered entirely by inbound FC frames processed asynchronously in the driver\u0027s interrupt/completion and workqueue contexts.

Heap grooming around the freed slab object yields an arbitrary-read primitive.\nI:H - lpfc_rq_buf_free() performs a list_del() write into the freed object and re-posts stale DMA addresses to the hardware RQ, causing the HBA to DMA attacker-supplied FC frame content into freed/reallocated kernel memory \u2014 a remote, attacker-controlled kernel write primitive, plus double-free-based heap control.\nA:H - The double kfree()/dma_pool_free() and freed-list corruption reliably produce slab corruption, BUG_ON in the allocator, or an oops in the interrupt-context completion handler, panicking the storage target host."

Title
batman-adv: fix OOB read/write in network-coding decode
Summary
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: fix OOB read/write in network-coding decode
batadv_nc_skb_decode_packet() trusts coded_len and checks only against
skb->len. XOR starts at sizeof(struct batadv_unicast_packet), reducing
payload headroom, and the source skb length is not verified, allowing an
out-of-bounds read and a small out-of-bounds write.
Validate that coded_len fits within the payload area of both destination
and source sk_buffs before XORing.

This is the classic same-broadcast-domain / WiFi-mesh injection scenario, i.e. Adjacent.\nAC:L - The attacker controls both halves of the primitive \u2014 the small buffered source frame (routed through the victim so send.c clones it into the decoding hash) and the oversized coded packet carrying coded_len, the MAC-based path key and the CRC packet_id, all computable offline. No race, no memory-layout guessing, and NC-capable nodes self-advertise via the BATADV_TVLV_NC OGM container, so the trigger is deterministic and repeatable.\nPR:N - batman-adv performs no authentication, encryption, or authorization on received frames; any node able to emit frames on the mesh segment reaches batadv_nc_recv_coded_packet(). No credentials, capabilities, or prior mesh membership approval are required.\nUI:N - The victim node processes the injected coded packet automatically in softirq receive context. No action by any user or administrator is needed beyond the mesh already running.\nS:U - The out-of-bounds read and write corrupt kernel heap memory within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The missing nc_packet-\u003eskb-\u003elen check allows reading roughly 1.4 KB of kernel heap past the buffered source skb, and because the data is XORed against attacker-known plaintext and then forwarded to an attacker-chosen orig_dest, the raw heap bytes are recovered remotely. This is a directly weaponizable kernel memory disclosure, not a bounded leak.\nI:H - The XOR overruns the destination skb by up to h_size (10) bytes with attacker-influenced content, landing in skb_shared_info (nr_frags, frag_list, dataref, gso fields) when tailroom is zero. Corrupting those fields drives bogus frag iteration and page puts in skb_release_data(), giving a heap-corruption/UAF primitive exploitable for control-flow hijack.\nA:H - The ~1.4 KB out-of-bounds read readily walks off the slab into unmapped memory, and the skb_shared_info overwrite corrupts refcounts and frag pointers, producing KASAN splats, oopses, or panics. The attacker can repeat this at will with no authentication."

cgwb_release
old wb released
wb_wakeup_delayed() accesses wb,
then trigger the use-after-free
issue
Fix this race condition by holding inode spinlock until
wb_wakeup_delayed() finished.

No network protocol handler is involved.\nAC:L - The attacker drives both sides of the race \u2014 a multi-threaded write() loop dirties the inode while the attacker forces cgroup writeback switches by dirtying the file from a second memcg and tearing that cgroup down, making the old wb\u0027s last reference drop. Attempts are unlimited and the bug was observed occurring spontaneously during normal boot, and CONFIG_CGROUP_WRITEBACK is default-y on all mainstream kernels.\nPR:L - Only an unprivileged local account with write access to a file on a writeback-capable filesystem (ext4/xfs home or /tmp) is needed; cgroup manipulation used to widen the race is available to ordinary users through systemd\u0027s delegated per-user cgroup subtree.\nUI:N - The attacker triggers everything itself through its own write() syscalls and cgroup activity; no victim action or interaction is required.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The freed bdi_writeback is dereferenced as `wb-\u003ebdi-\u003ecapabilities`, so a re-sprayed object yields an attacker-controlled pointer dereference and an arbitrary kernel-memory read primitive, enabling disclosure of arbitrary kernel data.\nI:H - wb_wakeup_delayed() writes into the freed object (spin_lock_irq on wb-\u003ework_lock) and inserts the freed `wb-\u003edwork` timer into the timer wheel, giving list-write primitives and an attacker-controlled `timer-\u003efunction` \u2014 a direct control-flow hijack path to arbitrary kernel code execution.\nA:H - The use-after-free reliably produces a kernel oops/panic as reported in the original crash trace (__mark_inode_dirty+0x124), and can be triggered repeatedly to crash the system."

Per kernel guidance, WiFi frame injection is Adjacent.\nAC:L - The attacker controls every precondition: SSID hiding, BSSID, the two channels, the beacon/probe-response pairs that build the hidden groups, and the CSA that fires `cfg80211_update_assoc_bss_entry()`; the victim\u0027s routine background scans supply the rest without attacker effort. The freed object\u0027s size is attacker-chosen via IE length, so heap grooming is also under attacker control.\nPR:N - No credentials or account on the target system are needed; beacons, probe responses and public action frames are unauthenticated and unprotected (beacon protection/BIGTK is rarely deployed), so a rogue AP or frame injector reaches the code with zero privileges.\nUI:N - Scanning, beacon processing and CSA handling are performed automatically by the kernel for an associated STA \u2014 no user action is required, and the attacker can spoof the legitimate AP\u0027s frames against an already-connected victim.\nS:U - The freed `cfg80211_bss_ies` allocation and all corrupted state live in the kernel\u0027s own slab and cfg80211 BSS list; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The stale `beacon_ies`/`ies` pointers are read by `cmp_bss()` and, critically, copied wholesale to userspace via `NL80211_BSS_BEACON_IES` in scan dumps, disclosing reallocated freed heap contents \u2014 and an attacker-controlled `len` after reallocation extends this to a large out-of-bounds kernel memory read.\nI:H - The shared IEs are freed while still owned by the beacon BSS, so the later `bss_free()` performs a second `kfree_rcu()` on the same object \u2014 a double free of an attacker-sized allocation, a well-established primitive for arbitrary write and control-flow hijack; freed-memory contents also drive rb-tree ordering decisions.\nA:H - Use-after-free reads in `cmp_bss()` plus the subsequent double free corrupt the slab allocator and reliably produce oopses/panics, and the condition can be re-triggered at will by an in-range attacker."

Title
Bluetooth: Fix use-after-free in l2cap_sock_cleanup_listen()
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix use-after-free in l2cap_sock_cleanup_listen()
syzbot reported the splat below without a repro.
In the splat, a single thread calling bt_accept_dequeue() freed sk
and touched it after that.
The root cause would be the racy l2cap_sock_cleanup_listen() call
added by the cited commit.
bt_accept_dequeue() is called under lock_sock() except for
l2cap_sock_release().
Two threads could see the same socket during the list iteration
in bt_accept_dequeue():
CPU1 CPU2 (close())
---- ----
sock_hold(sk) sock_hold(sk);
lock_sock(sk) <-- block close()
sock_put(sk)
bt_accept_unlink(sk)
sock_put(sk) <-- refcnt by bt_accept_enqueue()
release_sock(sk)
lock_sock(sk)
sock_put(sk)
bt_accept_unlink(sk)
sock_put(sk) <-- last refcnt
bt_accept_unlink(sk) <-- UAF
Depending on the timing, the other thread could show up in the
"Freed by task" part.
Let's call l2cap_sock_cleanup_listen() under lock_sock() in
l2cap_sock_release().

"value": "AV:A - The vulnerability lives in the Bluetooth L2CAP socket layer, and the objects that get freed and reused are child sockets that only ever exist because an adjacent Bluetooth peer established L2CAP connections to the listening PSM (`l2cap_connect_cfm` \u2192 `l2cap_sock_new_connection_cb`). The attack surface therefore spans the Bluetooth piconet/radio range.\nAC:L - The attacker controls both sides of the race \u2014 one thread blocked in `accept()` on the listening L2CAP socket and another calling `close()` on the same fd \u2014 and can retry indefinitely while keeping many pending children queued to widen the `bt_accept_dequeue()` iteration window. Nothing about the race depends on conditions outside the attacker\u0027s influence.\nPR:L - `l2cap_sock_create()` requires no capability for `SOCK_SEQPACKET`/`SOCK_STREAM` (only `SOCK_RAW` gates on `CAP_NET_RAW`), and binding a dynamic PSM \u2265 0x1001 bypasses the `CAP_NET_BIND_SERVICE` check, so an ordinary unprivileged local user can create, listen on, accept from and close the socket that triggers the race.\nUI:N - The race is driven entirely by the attacker\u0027s own threads performing `accept()` and `close()` syscalls plus inbound L2CAP connections; no victim action is needed.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The freed `struct sock` is read after free (`debug_spin_lock_before`/`release_sock`) and lives in a general kmalloc cache, so an attacker who sprays replacement objects into the freed slot can read back attacker-chosen or sensitive kernel data through the stale socket, giving an arbitrary-read path.\nI:H - After the free the kernel still writes into the object \u2014 `list_del_init()` on the freed `accept_q` node (an unlink write of attacker-groomable pointers), `sk_acceptq_removed()`, a refcount decrement, and spinlock stores \u2014 yielding a write primitive into reclaimed heap memory that is exploitable for control-flow hijack and privilege escalation.\nA:H - The bug is a confirmed slab use-after-free (syzbot KASAN splat) that corrupts the parent\u0027s accept queue list and takes a spinlock on freed memory, reliably producing an oops/panic and unbootable-level kernel instability."

"value": "AV:N - The crash is triggered by a remote peer\u0027s TCP connection plus a CLC Proposal message to an SMC-enabled listening socket, processed in smc_listen_work() on the smc_hs_wq workqueue. The triggering traffic is ordinary routable TCP (no RDMA fabric traffic is required to reach the fault), so any internet-reachable SMC server is exposed.\nAC:L - On an affected system (SMC-R backed by a soft-RoCE/rxe or siw device, a supported and commonly used configuration) the NULL dereference is hit unconditionally on the first SMC-R buffer mapping \u2014 no race, no heap grooming, no memory-layout dependency. The attacker fully controls the proposal fields that steer the server down the SMC-R v2 device path.\nPR:N - The entire path runs inside the CLC handshake worker before accept() returns to userspace, and SMC performs no authentication of the peer whatsoever. There are no capability checks anywhere in net/smc along this path.\nUI:N - The server-side handshake worker processes the attacker\u0027s connection automatically with no action by any local user or administrator.\nS:U - The fault and its consequences are confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The fault is a read of NULL+0x2ec (page fault error code 0000) that aborts immediately; no data is returned to the attacker and no out-of-bounds memory is disclosed.\nI:N - No memory is written and no attacker-controlled data corrupts kernel state \u2014 the dereference faults before dma_need_sync() can act.\nA:H - The NULL dereference oopses the smc_hs_wq kworker, killing it while it holds smc_server_lgr_pending and the socket lock, so the SMC subsystem deadlocks permanently for every later connection; with panic_on_oops the whole system panics, and the attacker can repeat it unauthenticated at will."
