Linux Kernel Thunderbolt Driver Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's Thunderbolt driver, specifically within the DisplayPort bandwidth request handling. The issue arises because memory allocated for bandwidth requests is not properly released after the requests are processed, leading to unnecessary memory consumption. This vulnerability affects the Linux kernel stable tree.

Impact

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

Remediation

Users can upgrade to the latest version of the Linux kernel stable tree to address this vulnerability. The patched version is included in the official Linux kernel releases.
