Use-After-Free Vulnerability in AMDGPU Display Driver of Linux Kernel

CVE-2026-31488

What is CVE-2026-31488?

A use-after-free vulnerability in the AMD GPU Display Driver for the Linux Kernel occurs when changes to Display Stream Compression (DSC) configurations are mismanaged. It arises during complex scenarios like simultaneous mode changes and external display connections, leading to the incorrect dropping of the mode_changed flag for the integrated panel. This fault can result in memory leaks and, ultimately, exploit opportunities. Proper synchronization in the management of CRTC states would prevent this issue, ensuring better stability and security.
