In the Linux kernel, the following vulnerability has been resolved: sockmap: Fix use-after-free in udp_bpf_recvmsg() syzbot reported use-after-free… (CVE-2026-74257)CVE-2026-74257 0 A use-after-free vulnerability in the Linux kernel's sockmap subsystem was identified and resolved. The flaw occurs in the udp_bpf_recvmsg() function due to improper serialization of sk_msg_recvmsg() calls, leading to potential concurrent access to freed memory. The issue was reported by syzbot and involves the handling of sk_msg structures without appropriate locking. The fix involves reintroducing lock_sock() serialization in udp_bpf_recvmsg() to prevent concurrent access. No specific affected versions are stated, and no CVSS score is available.
