Vulnerability Title
drm/vmwgfx: Unmap the surface before resetting it on a plane state
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Unmap the surface before resetting it on a plane state Switch to a new plane state requires unreferencing of all held surfaces. In the work required for mob cursors the mapped surfaces started being cached but the variable indicating whether the surface is currently mapped was not being reset. This leads to crashes as the duplicated state, incorrectly, indicates the that surface is mapped even when no surface is present. That's because after unreferencing the surface it's perfectly possible for the plane to be backed by a bo instead of a surface. Reset the surface mapped flag when unreferencing the plane state surface to fix null derefs in cleanup.
