This requires a rcu_head addition\nto the \"struct bpf_hrtimer\". Another kfree(t) happens in bpf_timer_init,\nthis does not need a kfree_rcu because it is still under the\nspin_lock and timer-\u003etimer has not been visible by others yet.\n\nIn bpf_timer_cancel, rcu_read_lock() is added because this helper\ncan be used in a non rcu critical section context (e.g. from\na sleepable bpf prog). Other timer-\u003etimer usages in helpers.c\nhave been audited, bpf_timer_cancel() is the only place where\ntimer-\u003etimer is used outside of the spin_lock.\n\nAnother solution considered is to mark a t-\u003eflag in bpf_timer_cancel\nand clear it after hrtimer_cancel() is done.  In bpf_timer_cancel_and_free,\nit busy waits for the flag to be cleared before kfree(t). This patch\ngoes with a straight forward solution and frees timer-\u003etimer after\na rcu grace period."

No remotely supplied data reaches `kernel/bpf/helpers.c`, and BPF is classified as a local attack vector under kernel scoring guidance.\nAC:L - The attacker owns both racers \u2014 one thread runs its own BPF program calling `bpf_timer_cancel()` while another deletes the map element or drops the map uref \u2014 and can widen the window arbitrarily by making its own timer callback long-running, since `hrtimer_cancel()` blocks in `hrtimer_cancel_wait_running()` while the other thread finishes and `kfree()`s `t`. Nothing depends on state outside the attacker\u0027s control and the sequence can be retried in a tight loop.\nPR:L - The `bpf_timer_*` helpers are gated on `bpf_capable()` (CAP_BPF/CAP_SYS_ADMIN), a reduced non-root capability routinely delegated to unprivileged service, tracing and container workloads that are not init-namespace root. This matches this CNA\u0027s established scoring for the sibling `bpf_timer` UAFs CVE-2024-41045 and CVE-2024-42239.\nUI:N - The attacker loads its own program, arms its own timer, and issues both the cancel and the map-delete from its own threads. No victim action, mount, or interaction with any other principal is required.\nS:U - The freed `struct bpf_hrtimer` and the corrupted per-CPU hrtimer state are entirely kernel-internal, so the impact stays within the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `hrtimer_active()` reads `timer-\u003ebase` out of the freed object and dereferences it (`base-\u003eseq`, `base-\u003erunning`), so reclaiming the 96-byte `kmalloc-cg-96` slot with sprayed data (e.g. `msg_msg`) turns this into an attacker-directed kernel-memory read, with the helper\u0027s return value acting as an oracle. That yields arbitrary kernel data disclosure and KASLR defeat.\nI:H - After `hrtimer_active()` returns true, `lock_hrtimer_base()` takes a spinlock at an attacker-controlled address and `remove_hrtimer()`/`__remove_hrtimer()` writes `timer-\u003estate`, performs `timerqueue_del()` rb-tree unlinking and clears bits in `cpu_base-\u003eactive_bases` through the same forged pointer. This is a controlled kernel write primitive suitable for privilege escalation.\nA:H - Even without a successful spray, operating on freed memory corrupts the per-CPU hrtimer queue and produces a KASAN splat, oops, or panic, and a garbage `timer-\u003ebase` sends `hrtimer_cancel()` into an unterminating retry loop. The attacker can trigger this at will, repeatedly."

There is no remote packet-processing path into ip6_route_multipath_add().\nAC:L - The attacker creates both sides of the condition: they drop the last reference themselves and can widen the window arbitrarily by supplying many nexthops, by setting RTA_EXPIRES=0 so the non-rtnl gc softirq reaps the route, and by lowering net.ipv6.route.gc_interval inside their own netns, with unlimited retries. syzbot reproduced it, confirming reliable triggerability.\nPR:L - rtnetlink_rcv_msg() only requires netlink_net_capable(skb, CAP_NET_ADMIN), which is evaluated against the network namespace\u0027s user namespace, so any unprivileged local user obtains it with `unshare -Urn`. Multipath ECMP routes are addable in that namespace using RTNH_F_ONLINK gateways, which bypasses gateway reachability validation.\nUI:N - The entire sequence is performed by the attacker\u0027s own process in a single netlink transaction; no victim action, mount, or other interaction is needed.\nS:U - The use-after-free corrupts kernel heap memory and is exploited within the same kernel security authority; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - rt6_fill_node() reads the freed kmalloc-512 fib6_info and copies its contents into an RTM_NEWROUTE netlink message returned to the attacker\u0027s socket, including dereferencing pointers taken from freed memory such as rt-\u003efib6_metrics (passed to rtnetlink_put_metrics()), rt-\u003efib6_table, and rt-\u003efib6_nh. Reclaiming the freed slot with controlled data turns this into an arbitrary kernel-memory read leaked directly to userspace.\nI:H - This is a use-after-free on a 512-byte kmalloc object that an unprivileged attacker can spray and reclaim, after which the kernel dereferences attacker-controlled pointers and performs a list_for_each_entry_safe() walk over the freed fib6_siblings list head. That yields controlled pointer traversal and corruption suitable for privilege escalation.\nA:H - The KASAN slab-use-after-free in rt6_fill_node() causes an oops/panic when the freed object is unmapped, poisoned, or reclaimed with invalid pointers, and it can be triggered repeatedly to reliably crash the kernel."

The second call attempts to remove the\n\"hash_list\" entry from a list, while it was already removed by the first\ncall.\n\nFix __dm_internal_resume so that it calls the preresume and resume\nmethods of the table\u0027s targets.\n\nIf a preresume method of some target fails, we are in a tricky situation.\nWe can\u0027t return an error because dm_internal_resume isn\u0027t supposed to\nreturn errors. We can\u0027t return success, because then the \"resume\" and\n\"postsuspend\" methods would not be paired correctly. So, we set the\nDMF_SUSPENDED flag and we fake normal suspend - it may confuse userspace\ntools, but it won\u0027t cause a kernel crash.\n\n------------[ cut here ]------------\nkernel BUG at lib/list_debug.c:56!\ninvalid opcode: 0000 [#1] PREEMPT SMP\nCPU: 1 PID: 8343 Comm: dmsetup Not tainted 6.8.0-rc6 #4\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014\nRIP: 0010:__list_del_entry_valid_or_report+0x77/0xc0\n\u003csnip\u003e\nRSP: 0018:ffff8881b831bcc0 EFLAGS: 00010282\nRAX: 000000000000004e RBX: ffff888143b6eb80 RCX: 0000000000000000\nRDX: 0000000000000001 RSI: ffffffff819053d0 RDI: 00000000ffffffff\nRBP: ffff8881b83a3400 R08: 00000000fffeffff R09: 0000000000000058\nR10: 0000000000000000 R11: ffffffff81a24080 R12: 0000000000000001\nR13: ffff88814538e000 R14: ffff888143bc6dc0 R15: ffffffffa02e4bb0\nFS:  00000000f7c0f780(0000) GS:ffff8893f0a40000(0000) knlGS:0000000000000000\nCS:  0010 DS: 002b ES: 002b CR0: 0000000080050033\nCR2: 0000000057fb5000 CR3: 0000000143474000 CR4: 00000000000006b0\nCall Trace:\n \u003cTASK\u003e\n ? die+0x2d/0x80\n ? do_trap+0xeb/0xf0\n ? __list_del_entry_valid_or_report+0x77/0xc0\n ? do_error_trap+0x60/0x80\n ? __list_del_entry_valid_or_report+0x77/0xc0\n ? exc_invalid_op+0x49/0x60\n ? __list_del_entry_valid_or_report+0x77/0xc0\n ? asm_exc_invalid_op+0x16/0x20\n ? table_deps+0x1b0/0x1b0 [dm_mod]\n ? __list_del_entry_valid_or_report+0x77/0xc0\n origin_postsuspend+0x1a/0x50 [dm_snapshot]\n dm_table_postsuspend_targets+0x34/0x50 [dm_mod]\n dm_suspend+0xd8/0xf0 [dm_mod]\n dev_suspend+0x1f2/0x2f0 [dm_mod]\n ? table_deps+0x1b0/0x1b0 [dm_mod]\n ctl_ioctl+0x300/0x5f0 [dm_mod]\n dm_compat_ctl_ioctl+0x7/0x10 [dm_mod]\n __x64_compat_sys_ioctl+0x104/0x170\n do_syscall_64+0x184/0x1b0\n entry_SYSCALL_64_after_hwframe+0x46/0x4e\nRIP: 0033:0xf7e6aead\n\u003csnip\u003e\n---[ end trace 0000000000000000 ]---"

There is no network or remote-peer input involved.\nAC:L - The attacker fully controls the entire trigger sequence with plain dmsetup ioctls \u2014 create a thin pool and a thin device whose table also carries a snapshot-origin (or cache/raid) segment, suspend and resume the pool, then suspend or remove the thin device. No race must be won and no unpredictable memory layout is required; the double `list_del()` / unbalanced `down_write()` is deterministic.\nPR:L - The dm ioctl path is administrative, but in the deployments where this matters (container runtimes using the devicemapper/thin storage driver, CSI storage plugins, privileged containers granted CAP_SYS_ADMIN, and appliances where LVM operations are delegated), the actor triggering it is a low-privileged tenant relative to the host kernel, consistent with how other device-mapper flaws in this subsystem are rated.\nUI:N - The attacker performs every step itself \u2014 table load, pool suspend/resume, device suspend/remove \u2014 through its own ioctl calls. No action by any other user or administrator is needed.\nS:U - The corruption and the resulting crash/hang are confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The unbalanced postsuspend/resume corrupts kernel state \u2014 a global linked list (`_dm_origins`) is operated on with stale/poisoned entries, and targets keep serving I/O with desynchronized mapping metadata (dm-cache migration state, dm-integrity journal/commit sequence, dm-snapshot origin registration), which is memory/state corruption that can be steered toward exposing kernel or foreign-volume data.\nI:H - This is a kernel list-corruption bug (double `list_del()` on `dm_origin-\u003ehash_list`), and the missing `.resume`/`.preresume` calls leave targets running with committed-but-not-reinitialized on-disk state \u2014 dm-integrity\u0027s journal is re-initialized and its autocommit timer deleted while writes continue, and dm-cache/dm-raid mapping state is left stale, permitting silent corruption of data stored on the mapped device.\nA:H - The reported failure is `kernel BUG at lib/list_debug.c:56` (invalid opcode oops) in `origin_postsuspend` reached from `dm_suspend`, taken while `_origins_lock` is write-held, so the box either panics or permanently wedges all further dm/snapshot operations. Equivalent unbalanced paths in dm-cache (`prevent_background_work` \u2192 unmatched `down_write`) and dm-raid1 (`dm_rh_stop_recovery`) produce unkillable hangs holding `md-\u003esuspend_lock`."

Fill_meta_index() is called to allocate (via empty_meta_index())\n   and fill a metadata index.  It however suffers a data read error\n   and aborts, invalidating the newly returned empty metadata index.\n   It does this by setting the inode number of the index to zero,\n   which means unused (zero is not a valid inode number).\n\n2. When fill_meta_index() is subsequently called again on another\n   read operation, locate_meta_index() returns the previous index\n   because it matches the inode number of 0.  Because this index\n   has been returned it is expected to have been filled, and because\n   it hasn\u0027t been, an out of bounds access is performed.\n\nThis patch adds a sanity check which checks that the inode number\nis not zero when the inode is created and returns -EINVAL if it is.\n\n[phillip@squashfs.org.uk: whitespace fix]"

No packet-processing path leads here, so exploitation requires local access to the host or to a passed-through VF.\nAC:L - The attacker drives both sides of the race himself \u2014 one thread spamming PF\u2192AF mailbox messages (e.g. unprivileged `ethtool -a`, which issues `cgx_cfg_pause_frm`) while another spams the VF\u2192AF doorbell on a separate MSI-X vector affined to a different CPU. No condition outside the attacker\u0027s control is required, and the race can be retried indefinitely at high rate.\nPR:L - Generating AF mailbox traffic needs only an ordinary local account \u2014 several octeontx2 ethtool GET operations (`get_pauseparam`, `get_fecparam`) send mailbox messages with no capability check \u2014 or possession of an SR-IOV VF exposed to a container/guest, which can write the mailbox trigger register directly. No root or CAP_NET_ADMIN in the initial namespace is required.\nUI:N - The attacker triggers both interrupt vectors entirely on his own by issuing ethtool/netdev requests and mailbox doorbell writes. No administrator or victim action is needed at any point.\nS:U - The corrupted mailbox bookkeeping and the resulting out-of-bounds accesses are all inside the host kernel, the same security authority as the vulnerable RVU AF driver. No hypervisor, IOMMU, or sandbox boundary is crossed by the corruption itself.\nC:H - When the concurrently-bumped `num_msgs` extends the loop in `__rvu_mbox_handler()` past the valid message list, `msg` is taken from unvalidated memory and `offset` is advanced by an unchecked 16-bit `next_msgoff`, producing out-of-bounds reads outside the 64 KB `ioremap_wc()` mailbox window whose contents are then acted on and echoed back in mailbox responses \u2014 an unbounded kernel read primitive.\nI:H - The same overrun performs an unconditional write (`msg-\u003epcifunc \u0026= ...; msg-\u003epcifunc |= ...`) at the attacker-influenced out-of-bounds offset before any signature validation, and the duplicate work-queue dispatch re-executes already-completed AF resource commands such as LF free/detach against released state, corrupting the admin function\u0027s resource tables.\nA:H - Duplicate processing of resource-teardown mailbox messages and out-of-range accesses to the ioremapped mailbox region readily oops the kernel, while the mutually-cleared interrupt bits drop mailbox events and wedge the AF\u2194PF/VF control plane, taking down all NIX/NPA networking on the SoC."
