| Vector | AV: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 6.6.58
Description
The issue is related to a NULL pointer dereference in the Linux kernel, specifically in the drm/amd/display component. This occurs when there is an attempt to recompute DSC parameters without a stream on the link. The problem arises under certain conditions involving MST (Multi-Stream Transport) and DSC (Display Stream Compression) setup. Technical details indicate that the
drm dp atomic find time slots function is involved, suggesting a potential issue with how time slots are managed for display port atomic operations. There is no information provided about the estimated number of potentially affected devices or real-world incidents where this issue was exploited.Recommendations
To resolve the issue, update the Linux kernel to version 6.6.58 or later. As a temporary workaround, consider disabling the
drm dp atomic find time slots function until a patch is available. However, this is not a recommended long-term solution due to potential impacts on display functionality.Exploit
