CVE-2026-23179

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nvmet-tcp: fixup hang in nvmet_tcp_listen_data_ready()<br /> <br /> When the socket is closed while in TCP_LISTEN a callback is run to<br /> flush all outstanding packets, which in turns calls<br /> nvmet_tcp_listen_data_ready() with the sk_callback_lock held.<br /> So we need to check if we are in TCP_LISTEN before attempting<br /> to get the sk_callback_lock() to avoid a deadlock.
