CVE-2026-74257

CVE-2026-74257 stems from a use-after-free in the Linux kernel sockmap path (udp_bpf_recvmsg) where sk_msg_recvmsg() can touch the same sk_msg when multiple threads race. The mitigation described in connected docs is to serialize sk_msg_recvmsg() by callers, specifically by adding a lock around u...
