Its embedded -\u003erefs\nhlist_head is exactly where epi-\u003efllink.pprev points, so the\nsubsequent hlist_del_rcu()\u0027s \"*pprev = next\" scribbles into freed\nkmalloc-192 memory.\n\nIn addition, struct file is SLAB_TYPESAFE_BY_RCU, so the slot\nbacking @file could be recycled by alloc_empty_file() --\nreinitializing f_lock and f_ep -- while ep_remove() is still\nnominally inside that lock. The upshot is an attacker-controllable\nkmem_cache_free() against the wrong slab cache.\n\nPin @file via epi_fget() at the top of ep_remove() and gate the\ncritical section on the pin succeeding. With the pin held @file\ncannot reach refcount zero, which holds __fput() off and\ntransitively keeps the watched struct eventpoll alive across the\nhlist_del_rcu() and the f_lock use, closing both UAFs.\n\nIf the pin fails @file has already reached refcount zero and its\n__fput() is in flight. Because we bailed before clearing f_ep,\nthat path takes the eventpoll_release() slow path into\neventpoll_release_file() and blocks on ep-\u003emtx until the waiter\nside\u0027s ep_clear_and_put() drops it. The bailed epi\u0027s share of\nep-\u003erefcount stays intact, so the trailing ep_refcount_dec_and_test()\nin ep_clear_and_put() cannot free the eventpoll out from under\neventpoll_release_file(); the orphaned epi is then cleaned up\nthere.\n\nA successful pin also proves we are not racing\neventpoll_release_file() on this epi, so drop the now-redundant\nre-check of epi-\u003edying under f_lock. The cheap lockless\nREAD_ONCE(epi-\u003edying) fast-path bailout stays."

Later,\nsctp_process_init() accesses INIT parameters unconditionally, which may\nlead to out-of-bounds reads.\n\nIn addition, raw_addr_list_len is not fully validated against the\nremaining cookie payload. When cookie authentication is disabled, an\nattacker can supply an oversized raw_addr_list_len and cause\nsctp_raw_to_bind_addrs() to read beyond the end of the cookie. The\naddress parser also lacks sufficient bounds checks for parameter headers\nand lengths, allowing malformed address parameters to trigger\nout-of-bounds reads.\n\nFix this by:\n\n- requiring the embedded INIT chunk length to be at least sizeof(struct\n  sctp_init_chunk);\n- validating that the INIT chunk and raw address list together fit\n  within the cookie payload;\n- verifying sufficient data exists for each address parameter header and\n  payload before parsing it.\n\nNote that sctp_verify_init() must be called after sctp_unpack_cookie()\nand before sctp_process_init() when cookie authentication is disabled.\nThis will be addressed in a separate patch."

Because the read is not strictly bounded to a few bytes and related SCTP COOKIE_ECHO bugs demonstrate kernel memory leakage potential, confidentiality impact is High.\nI:N - The investigated fix addresses out-of-bounds reads and missing length validation, not an out-of-bounds write or direct arbitrary memory modification primitive.

A local attacker can repeatedly exercise the NPU and trigger log printing or recovery.\nPR:L - The relevant DRM accel ioctls do not require capabilities, and the debugfs fw_log file is created as readable when debugfs is accessible. This is reachable by a local low-privileged user with access to the NPU device/debug interface, not by an unauthenticated remote attacker.\nUI:N - Exploitation does not require a separate victim action. The attacker can invoke the local device/debugfs path directly.\nS:U - The impact is within the local kernel/device driver security authority. It does not cross a VM, IOMMU, or other separate security scope boundary.\nC:H - Unbounded firmware-controlled indices can make the driver read far beyond the firmware log BO and print kernel memory through the log/coredump output path. This is an out-of-bounds read that can disclose high-value kernel memory.\nI:N - The vulnerable path reads bytes and prints them; it does not write out of bounds or provide an evident memory modification primitive. The fix only clamps read offsets.\nA:H - Out-of-bounds reads from a vmapped buffer can fault while walking unmapped memory or consume excessive resources while printing. This can cause a kernel oops/panic or serious denial of service."

When doing this, it checks whether\nthe preceding entry in acct-\u003ework_list has the same hash value, but\nnever checks that the predecessor is hashed at all. io_get_work_hash()\nis simply atomic_read(\u0026work-\u003eflags) \u003e\u003e IO_WQ_HASH_SHIFT, and the hash\nbits are never set for non-hashed work, so it returns 0. Thus, when a\nhashed bucket-0 work is cancelled while a non-hashed work is its list\npredecessor, the check spuriously passes and a pointer to the non-hashed\nio_kiocb is stored in wq-\u003ehash_tail[0].\n\nBecause non-hashed work is dequeued via the fast path in\nio_get_next_work(), which never touches hash_tail[], the stale pointer\nis never cleared. Therefore, after the non-hashed io_kiocb completes and\nis freed back to req_cachep, wq-\u003ehash_tail[0] is a dangling pointer. The\nio_wq is per-task (tctx-\u003eio_wq) and survives ring open/close, so the\ndangling pointer persists for the lifetime of the task; the next hashed\nbucket-0 enqueue dereferences it in io_wq_insert_work() and\nwq_list_add_after() writes through freed memory.\n\nAdd the missing io_wq_is_hashed() check so a non-hashed predecessor\nnever inherits a hash_tail[] slot."

It does not require routable IP network access, but does require proximity to the affected WiFi interface.\nAC:L - Once the event path is reachable, the attacker-controlled IF-event payload directly supplies the unchecked bsscfgidx and no race or hard-to-satisfy heap condition is required to trigger the out-of-bounds access. The higher-severity choice is appropriate because the malformed index is consumed deterministically.\nPR:N - In the highest reasonable WiFi-adjacent scenario, the attacker sends crafted wireless traffic/event data without any local account or administrative privilege on the victim. Local nl80211 interface creation has admin gating, but that is not the highest-severity reachable scenario for this driver class.\nUI:N - No victim action is required once the affected wireless interface is active in a reachable deployment. The vulnerable worker processes queued firmware events asynchronously without prompting the user.\nS:U - The corruption occurs within the host kernel driver and impacts the same kernel security authority. This is not a VM escape, IOMMU bypass, or cross-authority boundary change.\nC:H - The unchecked bsscfgidx indexes beyond drvr-\u003eiflist[], and subsequent paths can treat adjacent kernel memory as interface pointers. As kernel memory corruption, this can reasonably be leveraged for high-impact information disclosure.\nI:H - The IF_ADD path can write a newly allocated brcmf_if pointer through an out-of-bounds drvr-\u003eiflist[] slot, corrupting adjacent kernel state. This is an out-of-bounds write primitive and is scored as high integrity impact.\nA:H - Malformed indices can cause invalid pointer dereferences, bogus interface removal/reset operations, or broader kernel memory corruption. These conditions can crash or destabilize the kernel, so availability impact is high."

E.g., a message\nframe of type FRAME_TAG_AUTH_REPLY_MORE, that is just as long to hold\nthe ciphertext at its end with a ciphertext_len of 8 or less, can\ntrigger an out-of-bounds memory access when accessing hdr-\u003emagic.\n\nThis patch fixes the issue by adding a check to ensure that the\ndecrypted plaintext in the buffer is large enough to represent at least\nthe ceph_x_encrypt_header."

For example, if the\ntarget entry and following entries are swapped in or freed, then a large\nfolio was added in place and swapped out, using the same entry, the\nxa_cmpxchg_irq will still succeed, it\u0027s very unlikely to happen though.\n\nTo fix that, open code the Xarray cmpxchg and put the order retrieval and\nvalue checking in the same critical section.  Also, ensure the order won\u0027t\nexceed the end border, skip it if the entry goes across the border.\n\nSkipping large swap entries crosses the end border is safe here.  Shmem\ntruncate iterates the range twice, in the first iteration,\nfind_lock_entries already filtered such entries, and shmem will swapin the\nentries that cross the end border and partially truncate the folio (split\nthe folio or at least zero part of it).  So in the second loop here, if we\nsee a swap entry that crosses the end order, it must at least have its\ncontent erased already.\n\nI observed random swapoff hangs and kernel panics when stress testing\nZSWAP with shmem.

There is no race or external timing condition required.\nPR:L - A normal unprivileged local user can create IPv4 UDP sockets and use UDP_CORK/MSG_MORE/splice or related paged send paths; raw sockets are CAP_NET_RAW-gated but are not needed for the strongest local trigger. This is therefore basic local user privilege, not real administrator privilege.\nUI:N - No victim interaction is required once the attacker can run the local send/splice sequence. The vulnerable skb construction happens synchronously in the attacker-driven socket send path.\nS:U - The impact is within the same kernel security authority as the vulnerable IPv4 networking code. This is not a VM escape, IOMMU bypass, or cross-authority boundary violation.\nC:H - The bug under-allocates/accounting for the linear skb area and can copy attacker-controlled fraggap bytes past skb-\u003eend into trailing skb_shared_info metadata. Kernel memory corruption of this kind is reasonably capable of being developed into information disclosure, so the higher severity confidentiality value is appropriate.\nI:H - The copied fraggap bytes corrupt kernel skb metadata past the intended buffer boundary. This is an out-of-bounds write in kernel heap/networking structures and is scored as high integrity impact.\nA:H - The corrupted skb metadata can crash or destabilize the kernel networking stack, and related negative-copy accounting can also produce severe send-path failure behavior.

No local access or network adjacency is required.\nAC:H - Exploitation requires statistically extracting nanosecond-scale timing deltas from the early-exit `memcmp` across network jitter and target CPU load, and on 64-bit architectures with `HAVE_EFFICIENT_UNALIGNED_ACCESS` the loop leaks only 8-byte-granular prefixes \u2014 conditions the attacker cannot influence. The bad-signature path is a silent `sctp_sf_pdiscard()`, so no direct request/response oracle exists.\nPR:N - The COOKIE ECHO path is reached pre-authentication on any listening SCTP socket, with the attacker supplying both the cookie contents and the matching verification tag, so no credentials or prior association state are needed. Cookie HMAC signing is enabled by default via `CONFIG_SCTP_DEFAULT_COOKIE_HMAC_MD5`.\nUI:N - The vulnerable comparisons execute automatically in the SCTP receive path for every COOKIE ECHO or AUTH chunk that reaches a listening endpoint or established association. No action by any local user or administrator is involved.\nS:U - The forged-MAC consequences \u2014 spoofed association establishment, out-of-bounds reads, and softirq hangs \u2014 all occur inside the kernel of the targeted host. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - A forged cookie MAC yields a fully attacker-controlled `struct sctp_cookie` whose unvalidated `raw_addr_list_len` drives an unbounded walk in `sctp_raw_to_bind_addrs()`, reading far past the skb. A forged SCTP-AUTH HMAC additionally allows ASCONF Add-IP injection to redirect an established association\u0027s data stream to the attacker.\nI:H - Recovering the MAC constitutes a complete bypass of SCTP\u0027s state-cookie and SCTP-AUTH authentication, letting an off-path attacker forge cookies to establish spoofed associations and inject arbitrary authenticated chunks into existing ones. The attacker-controlled cookie is copied wholesale into the new association via `memcpy(\u0026retval-\u003ec, bear_cookie, ...)` and fed to `sctp_process_init()`.\nA:H - With the cookie MAC forged, `sctp_raw_to_bind_addrs()` at this commit has no bounds checks \u2014 a zero-length address parameter makes `addrs_len -= len` never progress, producing an infinite loop in softirq context, while an oversized length causes an OOB read that can oops the kernel. Forged AUTH chunks also permit tearing down established associations."

Remote RDMA traffic may later exercise a bad MR, but the vulnerable iterator is invoked by local userspace registration, not by network packet parsing.\nAC:L - There is no race or probabilistic condition; on an affected RDMA/IOMMU deployment the attacker controls the MR address, length, and access flags needed to request large aligned mappings. Hardware/IOMMU support is an environmental prerequisite for the affected subsystem, not an exploitation step beyond attacker control.\nPR:L - The uverbs device node is created world-accessible and MR registration does not require CAP_SYS_ADMIN or CAP_NET_ADMIN, though the process must be an unprivileged local user able to use the RDMA device and pin memory under its memlock limits. No real init-namespace root privilege is required.\nUI:N - After local access to the RDMA device, the attacker can perform the open/context/PD/MR registration sequence directly. No separate victim action is required.\nS:U - The impact remains within the kernel/RDMA device memory-management security authority. This is not a guest-to-host escape, IOMMU boundary bypass by a guest, or another cross-scope boundary change.\nC:H - The truncation can program wrong DMA addresses into RDMA memory translation tables for blocks after the overflow. With RDMA read-capable access, the resulting mistranslation can expose unintended memory reachable through the device mapping, so the higher defensible confidentiality impact is High.\nI:H - The same wrong DMA translation can be used with local or remote write-capable MR permissions to direct RDMA writes to unintended mapped memory. Because this is device DMA memory corruption rather than a bounded metadata error, the higher defensible integrity impact is High.\nA:H - Incorrect DMA translations can cause IOMMU/device faults, corrupted RDMA state, or repeated failures of registered memory operations. Given the kernel/device-level DMA fault surface and the requirement to choose the higher severity when uncertain, availability impact is High."

Any server using kTLS (nginx, HAProxy, NFS with TLS) is reachable over the network.\nAC:L - The attacker controls both sides of the race: they send TCP ACKs to trigger tls_write_space and initiate disconnect to trigger the close path. With repeated connection attempts and ACK flooding, the race window is reliably winnable.\nPR:N - No authentication or privileges are needed to establish a TCP connection and send ACKs to a kTLS-enabled server. The race is triggered during normal TCP processing before any application-level authentication occurs.\nUI:N - No user interaction is needed. The attacker connects to the server, sends ACKs, and disconnects to trigger the race. The server processes this automatically.\nS:U - The vulnerability results in kernel-level use-after-free within the same security authority (kernel space). There is no crossing of a virtualization or sandbox boundary.\nC:H - This is a use-after-free where the freed tls_sw_context_tx (freed via immediate kfree, not kfree_rcu) can be reallocated with attacker-influenced data. The UAF gives read access to reallocated memory contents, enabling arbitrary kernel memory disclosure.\nI:H - The UAF on the tls_sw_context_tx structure enables heap spraying to control the freed object\u0027s contents. The tx_work_handler then calls tls_tx_records through corrupted context pointers, enabling control flow hijacking and arbitrary code execution.\nA:H - The use-after-free on the embedded delayed_work struct causes kernel crashes when the workqueue attempts to execute the freed work item, resulting in kernel panic or oops."

The attacker must be in NFC range, so this is adjacent rather than local or internet-routable network access.\nAC:L - The attacker can drive the required LLCP packet sequence, for example closing a matched LLCP socket with a remote control PDU and then sending DISC or I/RR/RNR for the same SAP pair. No uncontrollable race or special memory layout condition is required to trigger the double put/unlock path.\nPR:N - The triggering input is unauthenticated NFC LLCP traffic from the peer and does not require an account or privileges on the victim. Any local NFC setup or listening service is an environmental prerequisite, not a privilege held by the attacker.\nUI:N - After the victim NFC subsystem/link is active and the attacker is in range, malicious LLCP frames are processed by the kernel receive path without further victim action. Proximity is already captured by AV:A.\nS:U - The vulnerability corrupts kernel socket lifetime state within the same kernel security authority. It does not cross a VM, hypervisor, IOMMU, or separate authorization boundary.\nC:H - The bug causes a refcount imbalance and use-after-free of an NFC LLCP socket object. Kernel UAFs are defensibly treated as enabling memory disclosure primitives under the required high-severity guidance.\nI:H - The freed socket object can potentially be reclaimed and controlled, turning the UAF into kernel memory corruption or control-flow/data-structure modification. Under the required guidance, UAF impact is high for integrity.\nA:H - The double release and double sock_put can produce refcount underflow, use-after-free, warnings, oopses, or crashes in kernel socket handling. A kernel crash or panic is high availability impact."

There is no network, adjacent, or physical packet/device-input path.\nAC:L - The attacker controls the supplied event-page handle and can allocate a buffer smaller than `KFD_SIGNAL_EVENT_LIMIT * 8`, making the fixed-size `memset` out-of-bounds deterministic. No race or external condition is required.\nPR:L - The path is available to unprivileged userspace with access to KFD/AMDGPU device nodes, and the relevant ioctls have no capability flag or `capable()` gate. This is low privilege, not real administrator privilege.\nUI:N - Once a local attacker can execute code and open the device, exploitation only requires issuing ioctls. No victim user action is needed.\nS:U - The corruption occurs inside the kernel driver and impacts the same kernel security authority. This is standard local kernel compromise/DoS, not a cross-scope escape such as guest-to-host or IOMMU boundary bypass.\nC:H - The bug is an out-of-bounds kernel write into memory adjacent to a kernel-mapped GPU buffer, and kernel memory corruption can reasonably be leveraged to disclose sensitive kernel memory. Following the higher-severity rule for memory corruption, confidentiality impact is High.\nI:H - The vulnerable `memset` writes attacker-triggered data beyond the allocated object, giving a kernel memory corruption primitive. Out-of-bounds writes are scored as High integrity impact because they can plausibly be developed into privilege escalation or control-flow/data corruption.\nA:H - The out-of-bounds kernel write can corrupt adjacent kernel memory and readily crash or destabilize the kernel even without full exploitation. Kernel oops, panic, or persistent GPU/kernel failure is a High availability impact."

The returned SysV IPC id still uses the normal\nindex encoding, so later lookup and removal can target the wrong slot. \nThis leaves the real IDR entry behind and breaks the IDR state for the\nobject.\n\nThe bug is in ipc_idr_alloc() in the checkpoint/restore path.\n\n1. ids-\u003enext_id is passed to:\n\n       idr_alloc(\u0026ids-\u003eipcs_idr, new, ipcid_to_idx(next_id), 0, ...)\n\n2. The zero upper bound makes the allocation effectively open-ended.\n   Once the valid SysV IPC tail is occupied, idr_alloc() can spill past\n   ipc_mni and allocate an entry beyond the valid IPC id range.\n\n3. The new object id is still encoded with the narrower SysV IPC index\n   width:\n\n       new-\u003eid = (new-\u003eseq \u003c\u003c ipcmni_seq_shift()) + idx\n\n4. Later removal goes through ipc_rmid(), which uses:\n\n       ipcid_to_idx(ipcp-\u003eid)\n\n   That truncates the real IDR index. An object actually stored at a\n   high index can then be removed as if it lived at a low in-range\n   index.\n\n5. For shared memory, shm_destroy() frees the current object anyway, but\n   the real high IDR slot is left behind as a dangling pointer.\n\n6. A subsequent walk of /proc/sysvipc/shm reaches the stale IDR entry\n   and dereferences freed memory.\n\nPrevent this by bounding the requested allocation to ipc_mni so the\ncheckpoint/restore path fails once the valid range is exhausted."

              "value": "AV:N - On a transparent bridge or traffic-shaping gateway configured with the RED qevent and act_ct, unauthenticated remote IP fragments reach red_enqueue() through normal receive, bridge-forwarding, and egress-qdisc processing. No local netlink access is required to trigger the deployed configuration.\nAC:L - The attacker controls fragment contents and ordering and can drive RED into deterministic hard-mark or drop conditions with sustained traffic. No race or condition outside the attacker\u0027s control must be won.\nPR:N - CAP_NET_ADMIN is required to create the vulnerable configuration, but a remote attacker sending fragments through an already configured appliance needs no privileges or authentication. Local triggering is also possible with namespaced CAP_NET_ADMIN.\nUI:N - Triggering requires only attacker-generated fragmented traffic and does not depend on a victim performing any action.\nS:U - The corruption occurs within the host kernel and compromises resources governed by that same security authority. This remains unchanged scope even when used for namespace escape or kernel privilege escalation.\nC:H - The reclaimable sk_buff use-after-free and corrupted defragmentation-tree links can be leveraged through attacker-controlled network heap spraying to disclose arbitrary kernel memory.\nI:H - RED overwrites linkage fields that overlap the defragmentation RB node and may free the object while it remains referenced, enabling subsequent writes through freed or attacker-reclaimed kernel objects and potential code execution.\nA:H - The dangling fragment-tree entry can cause immediate or deferred use-after-free, double-free, invalid tree operations, and kernel panic when another fragment arrives or the queue expires. The attacker can trigger this repeatedly with fragmented traffic."
