Despite the subsystem being a wireless PAN stack, the defect itself is in socket setup, not in frame processing.\nAC:H - The dangling pointer is only produced when `sk->sk_prot->hash()` or `->init()` returns non-zero, but `raw_hash()`, `dgram_hash()` and `dgram_init()` all unconditionally `return 0` in every affected version (2.6.31–6.12) and the raw proto has no `.init`, so the error branch is unreachable and the attacker cannot influence it.\nPR:L - Creating a `SOCK_DGRAM` AF_IEEE802154 socket needs no capability at all, so any unprivileged local user reaches `ieee802154_create()`; note the `!net_eq(net, &init_net)` guard means the call must be made in the initial netns, so user namespaces do not lower this further but also are not needed.\nUI:N - The attacker performs the whole sequence with a single `socket()` syscall from its own process. No victim action or interaction is involved.\nS:U - The freed `struct sock`/`struct dgram_sock` and the stale `sock->sk` reference both live entirely within the kernel's own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Per the use-after-free rubric, a stale `sock->sk` reference to a freed `dgram_sock` in the kmalloc-general caches would let an attacker reclaim the slab and read back attacker-shaped or leftover kernel data through subsequent socket operations.\nI:H - The same dangling reference would allow heap spraying of the reclaimed slot, giving control over function-pointer-bearing fields (`sk_prot`, `sk_destruct`, `sk_wq`) and thus a control-flow-hijack primitive rather than a mere data corruption.\nA:H - Any dereference of the freed `sock->sk` would fault or corrupt the socket hash lists, producing an oops or panic; the rubric treats all use-after-free conditions as high availability impact even when only partially exploited."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/ieee802154/socket.c"],"versions":[{"version":"9ec7671603573ede31207eb5b0b3e1aa211b2854","lessThan":"1d5fe782c0ff068d80933f9cfd0fd39d5434bbc9","status":"affected","versionType":"git"},{"version":"9ec7671603573ede31207eb5b0b3e1aa211b2854","lessThan":"14959fd7538b3be6d7617d9e60e404d6a8d4fd1f","status":"affected","versionType":"git"},{"version":"9ec7671603573ede31207eb5b0b3e1aa211b2854","lessThan":"2b46994a6e76c8cc5556772932b9b60d03a55cd8","status":"affected","versionType":"git"},{"version":"9ec7671603573ede31207eb5b0b3e1aa211b2854","lessThan":"e8bd6c5f5dc2234b4ea714380aedeea12a781754","status":"affected","versionType":"git"},{"version":"9ec7671603573ede31207eb5b0b3e1aa211b2854","lessThan":"b4982fbf13042e3bb33e04eddfea8b1506b5ea65","status":"affected","versionType":"git"},{"version":"9ec7671603573ede31207eb5b0b3e1aa211b2854","lessThan":"03caa9bfb9fde97fb53d33decd7364514e6825cb","status":"affected","versionType":"git"},{"version":"9ec7671603573ede31207eb5b0b3e1aa211b2854","lessThan":"b4fcd63f6ef79c73cafae8cf4a114def5fc3d80d","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/ieee802154/socket.c"],"versions":[{"version":"2.6.31","status":"affected"},{"version":"0","lessThan":"2.6.31","status":"unaffected","versionType":"semver"},{"version":"5.4.287","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.231","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.174","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.120","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.66","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.5","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.13","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"5.4.287"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"5.10.231"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"5.15.174"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"6.1.120"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"6.6.66"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"6.12.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"6.13"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/1d5fe782c0ff068d80933f9cfd0fd39d5434bbc9"},{"url":"https://git.kernel.org/stable/c/14959fd7538b3be6d7617d9e60e404d6a8d4fd1f"},{"url":"https://git.kernel.org/stable/c/2b46994a6e76c8cc5556772932b9b60d03a55cd8"},{"url":"https://git.kernel.org/stable/c/e8bd6c5f5dc2234b4ea714380aedeea12a781754"},{"url":"https://git.kernel.org/stable/c/b4982fbf13042e3bb33e04eddfea8b1506b5ea65"},{"url":"https://git.kernel.org/stable/c/03caa9bfb9fde97fb53d33decd7364514e6825cb"},{"url":"https://git.kernel.org/stable/c/b4fcd63f6ef79c73cafae8cf4a114def5fc3d80d"}],"title":"net:
