Linux Kernel VMWGFX Driver Null Pointer Dereference Vulnerability on Hardware Version 10

A vulnerability in the Linux kernel's VMWGFX graphics driver for Hardware version 10 has been fixed. This issue arose because Hardware version 10 lacks GB Surfaces, leading to the absence of a backing buffer for surface-backed framebuffers. Consequently, this situation caused a null pointer dereference, crashing the driver and resulting in a black screen.

Impact

Exploitation of this vulnerability caused a null pointer dereference, leading to a crash of the VMWGFX driver and a black screen.

Remediation

Users can download the patched version of the Linux kernel from the Linux kernel stable tree.
