CVE-2026-98925

The Linux kernel contains a vulnerability in bpf, sockmap where a BPF stream_verdict program performing a self-redirect (with BPF_F_INGRESS ) causes double-counting of tcp_sk->copied_seq. When sk_psock_verdict_apply() calls tcp_eat_skb(), it advances the sequence counter; however, the same pac...

CVE-2026-98588

The Linux kernel is vulnerable to an out-of-bounds write in the sockmap component. The root cause is that sock_map_alloc() fails to reject max_entries values greater than INT_MAX, while sock_map_free() uses a signed integer iterator to traverse the sks[] array. When a SOCKMAP is created with max_...
