CVE-2026-23179

The CVE affects the Linux kernel nvmet-tcp implementation. A deadlock could occur when a socket is closed during TCP_LISTEN because nvmet_tcp_listen_data_ready() is called with sk_callback_lock held; the fix adds a TCP_LISTEN check before acquiring the lock to avoid deadlock. The issue is resolve...
