**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 6.10.0 **Description** A page fault vulnerability has been resolved in the Linux kernel, specifically in the AMD GPU display driver. The issue arose due to a mismatch in the maximum surface definition, where the DC driver used two different values, MAX SURFACES and MAX SURFACE NUM. This led to a page fault when the cursor overlay mode was introduced for AMD display versions that support two overlay planes. The vulnerability was faced by Cosmic users. **Recommendations** To resolve the issue, update the Linux kernel to a version that includes the fix for the page fault vulnerability. Specifically, update to a version later than 6.10.0. As a temporary workaround, consider disabling the cursor overlay mode for AMD display versions that support two overlay planes until a patch is available.
