Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The vulnerability is related to the Linux kernel's drm/vmwgfx driver. The driver creates a debug file entry even when the corresponding ttm resource manager is not allocated, leading to a crash when trying to read from this file. A check has been added to create the debug file only when the corresponding ttm resource manager is allocated. The vulnerability can be exploited by reading from the /sys/kernel/debug/dri/0/mob ttm file, which can cause a crash.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
