Title
ublk: make sure ubq->canceling is set when queue is frozen
Summary
In the Linux kernel, the following vulnerability has been resolved:
ublk: make sure ubq->canceling is set when queue is frozen
Now ublk driver depends on `ubq->canceling` for deciding if the request
can be dispatched via uring_cmd & io_uring_cmd_complete_in_task().
Once ubq->canceling is set, the uring_cmd can be done via ublk_cancel_cmd()
and io_uring_cmd_done().
So set ubq->canceling when queue is frozen, this way makes sure that the
flag can be observed from ublk_queue_rq() reliably, and avoids
use-after-free on uring_cmd.

The window can be retried indefinitely at no cost, and ublk is enabled in mainstream distribution kernels.\nPR:L - `ublk_ctrl_add_dev()` explicitly allows a caller without CAP_SYS_ADMIN to create a device with `UBLK_F_UNPRIVILEGED_DEV`, with subsequent control commands gated only by `inode_permission()` on the owner-owned char device, so an ordinary local user can create, serve and issue I/O to a ublk device. Even for admin-created devices, the ublk server daemon and the exposed block device are routinely driven by non-root contexts.\nUI:N - The attacker performs every step itself \u2014 creating the device, running the server, submitting I/O, and tearing down the io_uring ring. No action by any other user or administrator is needed.\nS:U - The corruption is of an io_uring `io_kiocb` inside the kernel, exploited from a local process; impact stays within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free on the uring_cmd/`io_kiocb`: the freed object is re-read (`ioucmd-\u003etask_work_cb`, `req-\u003ectx`, `req-\u003eio_task_work`) after reallocation, and the resulting controlled call/deref can be steered into an arbitrary kernel-memory disclosure primitive via the io_uring completion path.\nI:H - `__io_uring_cmd_do_in_task()` writes `task_work_cb` and `io_task_work.func` into the already-freed request and links it onto the ring\u0027s task-work list, and `io_uring_cmd_work()` then performs an indirect call through a function pointer sourced from that freed, heap-sprayable slab object \u2014 a write plus control-flow-hijack primitive leading to privilege escalation.\nA:H - Even unweaponized, the double-use of the uring_cmd causes double completion and use-after-free of the io_uring request, producing kernel oops/panic; the sibling fix for the same pairing was reported as a reproducible kernel crash."

Title
nfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm()
Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm()
Lei Lu recently reported that nfsd4_setclientid_confirm() did not check
the return value from get_client_locked(). a SETCLIENTID_CONFIRM could
race with a confirmed client expiring and fail to get a reference. That
could later lead to a UAF.
Fix this by getting a reference early in the case where there is an
extant confirmed client. If that fails then treat it as if there were no
confirmed client found at all.
In the case where the unconfirmed client is expiring, just fail and
return the result from get_client_locked().

No local access to the server is needed.\nAC:L - The attacker controls its own side of the race and can issue unauthenticated SETCLIENTID_CONFIRM operations at arbitrary rate, and the vulnerable window (force_expire_client() parked in wait_event for cl_rpc_users to drain) stays open as long as the attacker keeps RPCs in flight, so the window is attacker-widened rather than narrow. The forced-expire trigger is an administrative action, but it is the documented response to exactly the kind of misbehaving client the attacker can pose as.\nPR:N - OP_SETCLIENTID_CONFIRM is ALLOWED_WITHOUT_FH/ALLOWED_ON_ABSENT_FS, so no filehandle or export access check is performed, and under the default AUTH_SYS/AUTH_NULL flavors the RPC credentials are self-asserted and never verified. Any host able to reach the NFS port can reach the bug.\nUI:N - The attack is completed entirely by the attacker\u0027s own NFS traffic; no victim opens a file, mounts a filesystem, or otherwise interacts. The concurrent client-expiry is a system/administrative state condition folded into Attack Complexity, not user interaction.\nS:U - The corrupted object (struct nfs4_client) and all consequences remain within the kernel of the NFS server; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed struct nfs4_client is used after free (fsnotify_dentry, nfsd4_probe_callback) and its slab can be re-occupied by attacker-groomed data, giving a path to disclose arbitrary kernel memory. Per kernel scoring guidance a UAF is scored C:H.\nI:H - The UAF yields concrete write primitives on freed memory \u2014 set_bit() on cl_flags, memcpy() into cl_cb_conn, and an unbalanced atomic_dec() in put_client_renew_locked() \u2014 plus a function-pointer dereference via nfsd4_run_cb(\u0026clp-\u003ecl_cb_null), which is exploitable for control-flow hijacking.\nA:H - The use-after-free reliably oopses or panics the NFS server; additionally renew_client_locked() hits WARN_ON(1) (fatal with panic_on_warn) and the cl_rpc_users underflow to -1 leaves force_expire_client() stuck forever in wait_event, producing an unkillable hung task."

Kernel panic - not syncing: Fatal exception
Kernel Offset: 0x31c00000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff)
---[ end Kernel panic - not syncing: Fatal exception ]---
The root cause is that unpoison_memory() tries to check the PG_HWPoison
flags of an uninitialized page. So VM_BUG_ON_PAGE(PagePoisoned(page)) is
triggered. This can be reproduced by below steps:
1.Offline memory block:
echo offline > /sys/devices/system/memory/memory12/state
2.Get offlined memory pfn:
page-types -b n -rlN
3.Write pfn to unpoison-pfn
echo <pfn> > /sys/kernel/debug/hwpoison/unpoison-pfn
This scenario can be identified by pfn_to_online_page() returning NULL.
And ZONE_DEVICE pages are never expected, so we can simply fail if
pfn_to_online_page() == NULL to fix the bug.

"value": "AV:A - The vulnerable code is the mt76 802.11 TX scheduler, driven entirely by wireless traffic; an attacker within radio range saturates the hardware TX ring (flooding probe/auth requests an AP must answer, or bulk traffic) and controls station add/remove via association and injected deauth frames. This is same-WLAN-segment reachability, matching the standard Adjacent classification for WiFi driver bugs.\nAC:L - Both required conditions are directly attacker-controlled \u2014 TX-ring saturation is produced by the attacker\u0027s own traffic flood (or by forcing a scan/channel change that sets MT76_RESET), and multiple queued wcids are the normal state of a multi-station AP. Slab grooming for the follow-on UAF write is likewise driven by attacker-timed association/disassociation, so no condition lies outside the attacker\u0027s influence.\nPR:N - No credentials on the target kernel are needed: unassociated frame injection (probe/auth request floods eliciting responses, deauth frames forcing station teardown) drives both the TX-ring saturation and the mt76_wcid_cleanup() path that dereferences the corrupted list, and an attacker on an open or guest WLAN holds no privilege on the AP either.\nUI:N - The corruption occurs inside the driver\u0027s tx worker and station-removal paths in response to attacker-generated frames alone. No action by any local user or administrator is required.\nS:U - The corrupted list heads and the resulting writes are all within the kernel\u0027s own memory and security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The dangling list nodes are traversed and dereferenced through stale on-stack pointers and through freed, reallocated mt76 station slab objects, and the resulting `list_del` write primitive can be leveraged to disclose kernel memory. Per the use-after-free / memory-corruption guidance this rates High.\nI:H - `list_del_init()` on an orphaned entry performs `next-\u003eprev = prev` / `prev-\u003enext = next`, writing kernel pointers into a stack frame already reused by another task and, after the neighbouring wcid is freed, into an attacker-groomable reallocated slab object \u2014 a controllable kernel write primitive suitable for control-flow hijacking.\nA:H - The bug permanently wedges TX for every orphaned station (their frames are never re-scheduled), and the cross-linked stale and live lists produce cycles that spin `while (!list_empty(\u0026tx_list))` forever under local_bh_disable() with phy-\u003etx_lock held, hanging the system; with CONFIG_DEBUG_LIST it is an immediate list-corruption BUG/oops."

The attacker needs local control of an assigned VF (guest VM or VF-owning container), so this is local reachability rather than network or adjacent.\nAC:L - The attacker fully controls every input \u2014 `num_tc` and per-TC `count` via ENABLE_CHANNELS, then `num_queue_pairs` and the qpair array via CONFIG_VSI_QUEUES \u2014 so shrinking `num_tc` to leave stale `ch[]` entries and then walking `idx` into them is deterministic on the first attempt with no memory grooming or race. The only precondition, spoofchk disabled, is inherent to any ADq-enabled SR-IOV deployment and is a standard runtime configuration.\nPR:L - The attacker only needs to drive the VF\u0027s admin queue \u2014 kernel/root inside the assigned guest, or possession of the VFIO device \u2014 which is a low-privileged position relative to the host PF driver under attack. No privileges of any kind on the host are required.\nUI:N - The malicious VF sends the virtchnl message sequence entirely on its own initiative. No host administrator or other user action is needed at any stage.\nS:C - The attacking VF sits in a guest VM (or VF-assigned container) while the stale-index read and the resulting hardware queue-context programming occur in the host PF driver\u0027s security authority. The corrupted resources \u2014 HMC LAN Tx/Rx contexts and QTX_CTL bindings of VSIs belonging to the PF or to other VFs \u2014 are outside the attacker\u0027s scope, crossing the guest/host and inter-tenant SR-IOV boundary.\nC:H - Using a stale `ch[idx].vsi_id`, the VF resolves and reprograms the Rx queue context of a VSI it does not own, setting `rx_ctx.base` from its own `dma_ring_addr` so another VSI\u0027s received traffic is DMA\u0027d into attacker-designated memory \u2014 interception of host and cross-guest traffic. On pre-5.2 kernels the same defect additionally reads past the end of `vf-\u003ech[]` into adjacent `struct i40e_vf` state.\nI:H - `i40e_config_vsi_rx_queue()` performs no ownership check and `i40e_config_vsi_tx_queue()` validates only the VF-supplied `info-\u003evsi_id`, so the stale ID lets the VF clear and rewrite the LAN HMC Tx/Rx contexts of a foreign VSI\u0027s queues and issue a `QTX_CTL` write rebinding that PF queue to itself. This is attacker-controlled modification of host- and peer-owned hardware state.\nA:H - Clearing and rewriting queue contexts belonging to the PF\u0027s main VSI or another guest\u0027s VSI stalls or wedges those queues, and out-of-range `pf_queue_id` values (`I40E_QUEUE_END_OF_LIST`) drive HMC operations that trigger adapter error paths, PF/VF reset storms and loss of host networking. The VF can repeat the sequence at will, and a downed host PF takes every guest on the adapter with it."
