The attacker only needs IP reachability to the bearer address, not link-layer adjacency.\nAC:L - The error path is entered whenever `tipc_msg_validate()` rejects the reassembled message, and every field it checks (version, header size, message size, length) lives in the attacker-supplied fragment payload, so a FIRST_FRAGMENT followed by a malformed LAST_FRAGMENT triggers the UAF deterministically. There is no race and no memory-layout condition outside the attacker\u0027s influence \u2014 skb heap grooming is done by the attacker\u0027s own packet stream.\nPR:N - TIPC neighbour discovery and link establishment (`tipc_disc_rcv` \u2192 `tipc_node_check_dest`) perform no authentication whatsoever; only a matching net_id (default 4711) is required, and TIPC_CRYPTO is a non-default option. An unauthenticated remote peer can bring up a link and immediately send the malicious fragment sequence.\nUI:N - The whole path executes in softirq/NAPI context on packet arrival with no involvement from any local user or application. No victim action of any kind is needed.\nS:U - The corruption is confined to kernel slab memory managed by the same kernel security authority; there is no crossing of a VM, IOMMU, or sandbox boundary. Impact is standard kernel-level compromise.\nC:H - This is a use-after-free/double-free of an skb: `kfree_skb_list_reason()` dereferences the freed fragment\u0027s `next` pointer, and the freed object can be reclaimed and filled with attacker-chosen data via network skb spraying, yielding a controlled read primitive and kernel memory disclosure.\nI:H - The coalesce path double-frees the skb into `skbuff_cache`, and the frag_list path causes `__kfree_skb()` on an attacker-controlled `next` pointer \u2014 classic type-confusion/arbitrary-free primitives that are leverageable into arbitrary kernel writes and control-flow hijack.\nA:H - The flaw is a KASAN-confirmed slab use-after-free plus double free in softirq context, which reliably oopses or panics the kernel on unpatched systems. It can be re-triggered at will by an unauthenticated remote peer for a persistent remote DoS."

The attacker only needs IP reachability to the bearer address, not link-layer adjacency.\\nAC:L - The error path is entered whenever `tipc_msg_validate()` rejects the reassembled message, and every field it checks (version, header size, message size, length) lives in the attacker-supplied fragment payload, so a FIRST_FRAGMENT followed by a malformed LAST_FRAGMENT triggers the UAF deterministically. There is no race and no memory-layout condition outside the attacker\u0027s influence \\u2014 skb heap grooming is done by the attacker\u0027s own packet stream.\\nPR:N - TIPC neighbour discovery and link establishment (`tipc_disc_rcv` \\u2192 `tipc_node_check_dest`) perform no authentication whatsoever; only a matching net_id (default 4711) is required, and TIPC_CRYPTO is a non-default option. An unauthenticated remote peer can bring up a link and immediately send the malicious fragment sequence.\\nUI:N - The whole path executes in softirq/NAPI context on packet arrival with no involvement from any local user or application. No victim action of any kind is needed.\\nS:U - The corruption is confined to kernel slab memory managed by the same kernel security authority; there is no crossing of a VM, IOMMU, or sandbox boundary. Impact is standard kernel-level compromise.\\nC:H - This is a use-after-free/double-free of an skb: `kfree_skb_list_reason()` dereferences the freed fragment\u0027s `next` pointer, and the freed object can be reclaimed and filled with attacker-chosen data via network skb spraying, yielding a controlled read primitive and kernel memory disclosure.\\nI:H - The coalesce path double-frees the skb into `skbuff_cache`, and the frag_list path causes `__kfree_skb()` on an attacker-controlled `next` pointer \\u2014 classic type-confusion/arbitrary-free primitives that are leverageable into arbitrary kernel writes and control-flow hijack.\\nA:H - The flaw is a KASAN-confirmed slab use-after-free plus double free in softirq context, which reliably oopses or panics the kernel on unpatched systems. It can be re-triggered at will by an unauthenticated remote peer for a persistent remote DoS.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
