In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Add a lock when accessing the buddy trim function

When running YouTube videos and Steam games simultaneously, the tester found a system hang / race condition issue with the multi-display configuration setting. Adding a lock to the buddy allocator's trim function would be the solution.
