Title
bpf, sockmap: Take state lock for af_unix iter
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Take state lock for af_unix iter
When a BPF iterator program updates a sockmap, there is a race condition in
unix_stream_bpf_update_proto() where the `peer` pointer can become stale[1]
during a state transition TCP_ESTABLISHED -> TCP_CLOSE.
CPU0 bpf CPU1 close
-------- ----------
// unix_stream_bpf_update_proto()
sk_pair = unix_peer(sk)
if (unlikely(!sk_pair))
return -EINVAL;
// unix_release_sock()
skpair = unix_peer(sk);
unix_peer(sk) = NULL;
sock_put(skpair)
sock_hold(sk_pair) // UaF
More practically, this fix guarantees that the iterator program is
consistently provided with a unix socket that remains stable during
iterator execution.

No remote network packet path reaches this iterator execution.\nAC:L - The attacker can create the AF_UNIX sockets, run the iterator read, and close the peer concurrently, controlling both sides of the race. No external victim timing or uncommon state is required beyond winning an attacker-orchestrated race.\nPR:L - The non-delegated path requires BPF-related capabilities, but BPF tokens can delegate the needed CAP_BPF/CAP_PERFMON/CAP_NET_ADMIN checks into a non-init user namespace. Under the higher-severity rule, this is best treated as reachable with low delegated local privileges rather than requiring init-namespace root.\nUI:N - No victim action is needed after the attacker has local execution and the required BPF access. The attacker triggers the iterator read and socket close directly.\nS:U - The bug corrupts kernel memory within the same OS security authority. It is not a VM escape, IOMMU bypass, or cross-scope boundary violation.\nC:H - The bug is a slab use-after-free on an AF_UNIX peer socket object during `sock_hold()`. Per kernel UAF guidance, this memory corruption can be leveraged for kernel memory disclosure in a plausible exploit.\nI:H - The stale peer pointer leads to a write to freed memory via the socket refcount increment. As a kernel UAF/write primitive, it is reasonably treated as enabling arbitrary corruption or control-flow compromise.\nA:H - The reported failure is a KASAN slab-use-after-free in kernel context and can crash or oops the kernel. Repeated local triggering can cause high availability impact."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
