**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 6.10.0 **Description** The issue is related to a divide error in the DM plane scale calculations in the Linux kernel's drm/amd/display module. The `dm get plane scale` function does not account for a plane scaled size equal to zero, leading to a kernel oops due to division by zero. This problem started with the introduction of cursor overlay mode, which uses the `dm get plane scale` function to assess cursor mode changes via `dm crtc get cursor mode` before checking the plane state. **Recommendations** To resolve the issue, update the Linux kernel to a version that includes the fix for the divide error in the DM plane scale calculations. Specifically, update to a version later than 6.10.0. Note: The provided information does not specify the exact version that includes the fix, so it is recommended to update to the latest available version to ensure the issue is resolved.
