Description

A flaw was found in the Linux kernel's handling of OpenVPN (Open Virtual Private Network) TCP (Transmission Control Protocol) connections. A race condition can occur when a userspace process closes a socket while a peer is in the kernel's release list. This can lead to a null pointer dereference when the kernel attempts to detach from the socket, causing a system crash and resulting in a Denial of Service (DoS).
