Description

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix KMS with 3D on HW version 10 HW version 10 does not have GB Surfaces so there is no backing buffer for surface backed FBs. This would result in a nullptr dereference and crash the driver causing a black screen.
