UnknownEPSS 0.17%

Last modified

CVE-2026-23179 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: fixup hang in nvmet_tcp_listen_data_ready() When the socket is closed while in TCP_LISTEN a callback is run to flush all outstanding packets, which in turns calls nvmet_tcp_listen_data_ready() with the sk_callback_lock held. So we need to check if we are in TCP_LISTEN before attempting to get the sk_callback_lock() to avoid a deadlock.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
