A fix is available — apply it.

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

drm/vmwgfx: Create debugfs ttm_resource_manager entry only if needed

The driver creates /sys/kernel/debug/dri/0/mob_ttm even when the corresponding ttm_resource_manager is not allocated. This leads to a crash when trying to read from this file.

Add a check to create mob_ttm, system_mob_ttm, and gmr_ttm debug file only when the corresponding ttm_resource_manager is allocated.
