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."

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."

In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory.

This\ncan leave part of the write region un-COW\u0027d.\n\nFix by moving skb_ensure_writable() inside the per-key loop where\nthe actual write offset is known, and add overflow checking on the\noffset arithmetic.

The partial COW condition is deterministic once suitable shared or page-cache-backed skbs are generated.\nPR:L - Installing the pedit action through RTM_NEWTFILTER requires CAP_NET_ADMIN in the network namespace. With unprivileged user namespaces, a basic local user can obtain namespace CAP_NET_ADMIN, so this is Low rather than High.\nUI:N - The attacker can configure the tc action and generate the triggering traffic without requiring any victim action. No user needs to open a file, mount a filesystem, or interact with crafted data.\nS:U - The vulnerability is in the kernel networking subsystem and impacts kernel-managed memory and page cache within the same security authority. It is a standard local kernel privilege-escalation/data-corruption issue, not a VM escape or separate-scope boundary bypass.\nC:H - The bug permits corruption of shared skb/page-cache memory outside the intended COW range, which is kernel memory/data corruption. Such corruption is defensibly usable for privilege escalation, after which protected information can be read.\nI:H - The vulnerable path gives attacker-influenced writes into shared page-cache-backed packet data that should have been private. This can corrupt protected data or code pages and is defensibly a high-integrity arbitrary data modification primitive.\nA:H - Repeated page cache or kernel memory corruption can crash the kernel, corrupt critical cached files, or destabilize networking and userspace execution. A kernel crash or system-wide corruption warrants 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."

No race or unusual victim state is required once the kernel client connects to the attacker-controlled peer.\nPR:N - The vulnerable parsing occurs in the authentication handshake before the remote peer has been authenticated by the kernel client. The attacker needs no privileges on the vulnerable system.\nUI:N - In a reasonable deployment, a configured kernel Ceph client connects or reconnects to its Ceph peers automatically. Exploitation does not require an interactive victim action at trigger time.\nS:U - The impact is within the kernel/client system processing the Ceph protocol. It does not cross a separate security authority such as a guest-to-host or IOMMU boundary.\nC:N - The bug is a bounded out-of-bounds read of the CephX encryption header magic field, but the read value is only compared internally and is not returned to the attacker. There is no practical information disclosure primitive.\nI:N - The vulnerable code performs no write based on the out-of-bounds access. The fix adds a read-side length check and there is no memory corruption or data modification path.\nA:H - The peer-controlled short plaintext can trigger an out-of-bounds kernel memory access in the auth receive path.
