**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the handling of plane refcount in the Linux kernel's drm/amd/display module. The mechanism to backup and restore plane states does not maintain the refcount, which can cause problems if the refcount of the plane changes between backup and restore operations. This can lead to memory leaks if the refcount was supposed to go down, or double frees/invalid memory accesses if the refcount was supposed to go up. The fix involves caching and re-applying the current refcount when restoring plane states. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the drm/amd/display component of the Linux kernel, where two problems have been fixed: a comparison with a wider integer type in a loop condition that can cause infinite loops, and a pointer dereference before a null check. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
