CVE-2026-74385
7.5
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
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.
