Description

A flaw was found in the nvmet-tcp component of the Linux kernel. This vulnerability arises from ignoring the return value of a function during the TLS handshake, specifically when the network socket is not in an established state. This oversight prevents proper cleanup, leading to the leakage of queues and sockets. An attacker could potentially exploit this issue to cause resource exhaustion, resulting in a Denial of Service (DoS).
