CVE-2024-50003

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

Description: A flaw in the Linux kernel has been identified, causing the system to hang when resuming with a Thunderbolt (TBT) monitor. This issue occurs because the TBT monitor HPD is triggered during the resume procedure, calling the drm client modeset probe() function while struct drm connector connector->dev->master is NULL, which messes up the pipe topology after resume.

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 skipping the TBT monitor HPD during the resume procedure. Restrict access to the drm client modeset probe() function to minimize the risk of exploitation until the issue is resolved.
