Linux Kernel WireGuard Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's WireGuard implementation. The issue arises in the socket handling of IPv6 packets when IPv6 is disabled. Specifically, the function responsible for sending data over WireGuard sockets fails to free the associated memory buffer, leading to a memory leak. This vulnerability has been addressed in a recent patch.

Impact

Exploitation of this vulnerability leads to a memory leak, where allocated memory is not properly released, potentially causing increased memory usage and degradation of system performance over time.

Remediation

Users can apply the latest patch available in the Linux kernel repository to address this vulnerability.
