CVE-2026-74268

This CVE describes a Linux kernel vulnerability where a child socket can inherit BPF sock_ops cb flags from the listener through sk_clone_lock(), leading to a crash or compromised handling if its setup fails in tcp_v4_syn_recv_sock() or tcp_v6_syn_recv_sock(). The root cause is that, on forced-cl...

CVE-2026-72447

CVE-2026-72447 (Linux kernel SCTP diag leak) : The vulnerability concerns SCTP_DIAG endpoint dumping in the Linux kernel, where SCTP endpoint address lists were read without holding lock_sock(), allowing concurrent socket operations (e.g., bindx) to change data. This race can cause nla_reserve() ...

CVE-2026-68284 bpf, sockmap: Fix cork use-after-free in tcp_bpf_sendmsg()

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix cork use-after-free in tcpbpfsendmsg tcpbpfsendmsg keeps msgtx across skstreamwaitmemory, which drops and reacquires the socket lock. Its error path tries to decide whether msgtx names the local temporary messag...

CVE-2026-64518

A flaw was found in the Linux kernel's TCP implementation. An out-of-bounds access vulnerability exists when the lockdepsockisheld function is called with a tcptimewaitsock object. This occurs because the tcptimewaitsock object lacks the necessary sk-sklock, leading to an incorrect lockdep...
