CVE-2024-46712: In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Disable coherent dumb buffers without 3

A vulnerability in the Linux kernel's vmwgfx driver (which manages graphics for virtual machines) allowed coherent dumb buffers (memory areas used for graphics that stay synchronized between the virtual machine and host) to be used even when 3D graphics acceleration was disabled, wasting resources and causing graphics memory to run out on low-memory systems. The fix ensures these buffers are only created when 3D graphics support is actually enabled.
