CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.52
Description The issue is related to the Linux kernel, specifically in the drm/amd/display component. The problem arises because the DC LOG DC should be run after checking link->link enc, not before. This fixes a REVERSE INULL issue reported by Coverity.
Recommendations Update to Linux kernel version 6.6.52 or later to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable drm/amd/display component until a patch is available.
