Linux Kernel Cache Stream Vulnerability in AMD Display Driver LT Automation

A vulnerability in the Linux kernel's AMD display driver can lead to a crash during Link Training (LT) automation. This issue arises because the process references the current state and updates planes and streams, which can disrupt the current state. The vulnerability affects the Linux kernel stable tree.

Impact

The vulnerability can cause a system crash by disrupting the current state management during the Link Training automation process.

Reproduction

The vulnerability can be reproduced by performing Link Training automation with the AMD display driver in the Linux kernel. The process will reference the current state and update planes and streams, leading to a crash.

Remediation

Users can apply the available patch in the Linux kernel stable tree to address this vulnerability.
