CVE-2024-49912

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.58

Description: A null pointer dereference issue has been identified in the Linux kernel, specifically in the drm/amd/display component. The problem arises when the stream status is null in the planes changed for existing stream function. Previously, the code assumed stream status could be null but failed to handle this case, leading to a potential null pointer dereference. This issue was reported by smatch.

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 applying a null check for stream status in the planes changed for existing stream function to prevent null pointer dereferences.
