CVE-2024-49921

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 6.11.2
Description: A null pointer dereference issue has been identified in the Linux kernel, specifically in the drm/amd/display component. The issue arises when pointers, such as dc->clk mgr, are not properly checked for null values before being used. This has resulted in 10 FORWARD NULL issues being reported by Coverity. The problem occurs because these pointers are null checked previously in the same function, but Coverity warns that they might still be null when used again.
Recommendations: For Linux kernel versions prior to 6.11.2, upgrade to a version that includes the fix for this issue to mitigate the risk of null pointer dereference.
