VectorAV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Linux Kernel (affected versions not specified)
Description The issue is related to a double-free vulnerability in the handling of vmw buffer object objects in the vmwgfx driver. This vulnerability occurs due to the lack of validation of an object's existence before performing further free operations, which may allow a local privileged user to escalate privileges and execute code in the context of the kernel. The vulnerability is associated with a race condition in the vmw user bo lookup() function.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
