Overview

About vulnerability

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.
