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.

kernel: drm/vmwgfx: Fix KMS with 3D on HW version 10
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.
A NULL pointer dereference vulnerability was found in the Linux kernel's VMware graphics (vmwgfx) driver. On VMware hardware version 10, which lacks GB Surfaces support, attempting to use 3D acceleration with KMS (Kernel Mode Setting) causes the driver to dereference a NULL backing buffer pointer for surface-backed framebuffers. This results in a kernel crash and black screen.
Statement: This vulnerability specifically affects VMware virtual mac
