CVE-2026-53184

The CVE-2026-53184 issue affects the Linux kernel UDP sockmap path. On UDP receive, skb->dev is repurposed as dev_scratch; when a SK_SKB verdict program uses BPF socket-lookup helpers (bpf_sk_lookup_tcp/udp, bpf_skc_lookup_tcp), skb->dev may still hold the dev_scratch value, and dev_net(skb...
