CVE-2023-52625

The CVE-2023-52625 entry concerns the Linux kernel’s drm/amd/display path (DMCUB enter/exit idle). The root cause is a SW/state mismatch when exiting idle before issuing commands to DMCUB, where the exit/notify idle operation can itself issue a command. The provided fix strategy is to track a sof...

CVE-2023-52624

CVE-2023-52624 concerns the Linux kernel’s drm/amd/display path where the DMCUB must be awake before issuing GPINT commands. The root cause is that GPINT mailbox access could occur while DMCUB is idle, risking a system hang. The documented fix adds a wake/execute/sleep wrapper via the function dc...
