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." } ] } ],
