In the Linux kernel, the following vulnerability has been resolved:
nvmet-tcp: check return value of nvmet_tcp_set_queue_sock
The return value of nvmet_tcp_set_queue_sock() is currently ignored in
nvmet_tcp_tls_handshake_done(). If it fails (e.g., due to the socket
not being in TCP_ESTABLISHED state), the socket callbacks will not be
properly set, leading to queue and socket leakage.
Fix this by capturing the return value and calling
nvmet_tcp_schedule_release_queue() on failure to ensure proper cleanup.
