"value": "AV:L - The vulnerable code is only reachable through the local `socket(2)` syscall path (`__sock_create` → `inet_create`); no remote peer input is involved. Exploitation requires the attacker to execute code on the target system.\nAC:L - The failure paths are triggered deterministically and unconditionally by an attacker-chosen syscall — `socket(AF_INET, SOCK_DGRAM, IPPROTO_ICMP)` fails in `ping_init_sock()` with -EACCES under the common default `ping_group_range` of \"1 0\", and the attacker can repeat it arbitrarily to groom the heap. No race and no attacker-uncontrollable precondition is involved.\nPR:L - Any ordinary unprivileged local user can call `socket()`; the ICMP-datagram and MPTCP paths involve no capability check at all, and the `SOCK_RAW` variant's `CAP_NET_RAW` is `ns_capable(net->user_ns, ...)`, obtainable via `unshare -Urn`.\nUI:N - The attacker triggers the whole sequence from their own process with a single syscall; no action by any other user or administrator is needed.\nS:U - The dangling pointer and any resulting corruption stay within the kernel's own security authority — this is a standard local kernel memory-safety issue with no VM, IOMMU, or sandbox boundary crossed.\nC:H - `sock->sk` is left pointing at a `struct sock` already freed by `sk_common_release()`; any subsequent dereference reads reclaimed slab memory whose contents the attacker can spray, yielding disclosure of kernel data and pointers.\nI:H - A use-after-free on a `struct sock` — an object dense with function pointers (`sk_destruct`, `sk_backlog_rcv`, `sk_prot` ops) — gives an attacker who reclaims the freed slab a write/control-flow-hijack primitive, so integrity impact must be treated as High.\nA:H - Dereferencing the stale `sk` pointer corrupts or faults on freed memory, producing a kernel oops or panic; the trigger is a single unprivileged syscall that can be repeated at will."
