CVE-2026-23008

Estado: AnalizadaMedia (5.5)—

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.
