Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.58
Description
A vulnerability in the Linux kernel has been resolved, specifically in the drm/amd/display component. The issue arises from the functions
dp enable link phy and dp disable link phy potentially passing link res without initializing hpo dp link enc, necessitating a null check before dereferencing to prevent FORWARD NULL issues. This vulnerability was reported by Coverity.Recommendations
For Linux kernel versions prior to 6.6.58, update to version 6.6.58 or later to resolve the issue. As a temporary workaround, consider adding null checks for
hpo dp link enc before using it in the dp enable link phy and dp disable link phy functions until a patch is applied.Exploit
