"value": "AV:L - The vulnerable path is reached through local AMD KFD/amdgpu device ioctls, especially acquiring an amdgpu render-node VM through /dev/kfd. No network or physical-device packet path reaches this code.\nAC:L - The race is between attacker-controlled processes sharing the same drm_file after fork and issuing concurrent VM-acquire operations. Because the attacker controls both sides of the race, this is low complexity.\nPR:L - An unprivileged local user with access to /dev/kfd and the amdgpu render node can issue the relevant ioctls; no real root or init-namespace capability check is required. This is basic local user access rather than administrative privilege.\nUI:N - Exploitation does not require a victim user action after the attacker has local execution and device access. The attacker can open the device files, fork, and invoke the ioctls directly.\nS:U - The bug corrupts kernel driver state within the same kernel security authority. It is a standard local kernel memory-corruption/privilege-escalation scenario, not a VM escape or other scope change.\nC:H - The non-atomic VM ownership assignment can leave stale amdkfd_process_info references and cause a kernel use-after-free. Following kernel UAF scoring guidance, this can be leveraged for high-impact information disclosure.\nI:H - The freed process_info object contains list, mutex, fence, and process state used later by KFD/GPUVM paths, making this kernel memory corruption. A defensible worst case is arbitrary kernel memory modification or control-flow influence.\nA:H - Even without full exploitation, the UAF and associated list/lifetime corruption can crash or hang the kernel. Kernel oops/panic-level denial of service is high availability impact."

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: purge outqueue on stale COOKIE-ECHO handling\n\nsctp_stream_update() is only invoked when the association is moved into\nCOOKIE_WAIT during association setup/reconfiguration. In this path, the\noutbound stream scheduler state (stream-\u003eout_curr) is expected to be\nclean, since no user data should have been transmitted yet unless the\nstate machine has already partially progressed.\n\nHowever, a corner case exists in sctp_sf_do_5_2_6_stale(): when a\nStale Cookie ERROR is received, the association is rolled back from\nCOOKIE_ECHOED to COOKIE_WAIT. In this scenario, user data may already\nhave been queued and even bundled with the COOKIE-ECHO chunk.\n\nDuring the rollback, sctp_stream_update() frees the old stream table\nand installs a new one, but it does not invalidate stream-\u003eout_curr.\nAs a result, out_curr may still point to a freed sctp_stream_out\nentry from the previous stream state.\n\nLater, SCTP scheduler dequeue paths (FCFS, RR, PRIO, etc.) rely on\nstream-\u003eout_curr-\u003eext, which can lead to use-after-free once the old\nstream state has been released via sctp_stream_free().\n\nThis results in crashes such as (reported by Yuqi):\n\n BUG: KASAN: slab-use-after-free in sctp_sched_fcfs_dequeue+0x13a/0x140\n Read of size 8 at addr ff1100004d4d3208 by task mini_poc/9312\n CPU: 1 UID: 1001 PID: 9312 Comm: mini_poc Not tainted\n 7.1.0-rc1-00305-gbd3a4795d574 #5 PREEMPT(full)\n sctp_sched_fcfs_dequeue+0x13a/0x140\n sctp_outq_flush+0x1603/0x33e0\n sctp_do_sm+0x31c9/0x5d30\n sctp_assoc_bh_rcv+0x392/0x6f0\n sctp_inq_push+0x1db/0x270\n sctp_rcv+0x138d/0x3c10\n\nFix this by fully purging the association outqueue when handling the\nStale Cookie case. This ensures all pending transmit and retransmit\nstate is dropped, and any scheduler cached pointers are invalidated,\nmaking it safe to rebuild stream state during COOKIE_WAIT restart.\n\nUpdating only stream-\u003eout_curr would be insufficient, since queued\nand retransmittable data would still reference the old stream state and\ntrigger later use-after-free in dequeue paths."

Per kernel CVSS guidance, use-after-free memory corruption can be leveraged for high confidentiality impact.\nI:H - The stale pointer use-after-free is kernel heap memory corruption and may be exploitable beyond a crash via heap manipulation.

"value": "AV:N - The vulnerable netfilter match, ipset, and logging paths run while processing packets in receive/netdev hooks. In a reasonable firewall, router, VPN, or tunnel deployment with these rules installed, unauthenticated remote packets can reach the vulnerable code.\nAC:L - No race or difficult timing is required; a packet reaching a vulnerable rule with an invalid, unset, non-Ethernet, or too-short MAC header deterministically drives the bad eth_hdr(skb) access. The needed rule/interface setup is a plausible deployment condition, not an exploit race.\nPR:N - The remote packet sender does not need credentials or local privileges once the affected rule or logger is configured. Although rule installation requires CAP_NET_ADMIN, that is not required for the runtime remote-trigger scenario.\nUI:N - Exploitation is triggered by packet processing and does not require a victim user to open a file, mount anything, or perform another action.\nS:U - The impact remains within the kernel/network stack security authority. There is no VM, IOMMU, or separate sandbox boundary crossing.\nC:H - The flaw causes invalid or out-of-bounds reads from the skb MAC header, and those bytes can be copied into logs/ipset state or influence observable match behavior. Per the required guidance, out-of-bounds reads are scored High when not proven strictly harmless.\nI:L - The primitive is a read rather than an arbitrary write or control-flow hijack. However, the wrongly read MAC bytes can influence firewall matches and ipset add/delete/test behavior, giving limited integrity impact.\nA:H - Invalid eth_hdr(skb) access can produce slab out-of-bounds/KASAN reports or kernel oops/panic conditions, and packets can be sent repeatedly. Kernel crashes are High availability impact."

The attacker can create the sockets, pass FDs, trigger GC, and race MSG_PEEK independently.\nS:U - The impact remains within the kernel/local IPC security authority. This is not a VM escape, IOMMU bypass, or other cross-scope boundary violation.\nC:N - The bug causes stale GC liveness decisions and purging of live AF_UNIX receive queues, but I did not find a new arbitrary read or unintended disclosure primitive. MSG_PEEK-visible descriptors are already exposed to the receiving endpoint by design.\nI:H - The race can make GC incorrectly collect a live AF_UNIX SCC and purge live receive queues, dropping queued data and SCM_RIGHTS file descriptors. That is unauthorized corruption/destruction of kernel-maintained IPC state, so integrity impact is High.\nA:H - The attacker can repeatedly cause live AF_UNIX sockets to lose queued messages and passed FDs, breaking IPC semantics and potentially denying service to affected local components. Under the required higher-severity rule, this supports High availability impact."

This is not a local userspace or IP network\npath; the attacker must be able to inject fabric traffic, for example as\na compromised switch or fabric controller, or as a same-zone N_Port on a\nfabric that permits source spoofing.\n\nThe Link-Integrity and Peer-Congestion FPIN walkers used a u8 loop\ncounter against the 32-bit on-wire pname_count field, and did not bound\npname_count by the descriptor body already validated by the TLV walker.\nA pname_count of 256 therefore wraps the counter and keeps the loop\ncondition true indefinitely.\n\nFactor the shared pname_list[] walk into one helper, widen the counter\nto u32, and clamp pname_count against the entries that fit in the\ndescriptor body before iterating."
