Description

drm/vmwgfx: Disable coherent dumb buffers without 3d

In the Linux kernel, the following vulnerability has been resolved:

drm/vmwgfx: Disable coherent dumb buffers without 3d

Coherent surfaces make only sense if the host renders to them using

accelerated apis. Without 3d the entire content of dumb buffers stays

in the guest making all of the extra work they're doing to synchronize

between guest and host useless.

Configurations without 3d also tend to run with very low graphics

memory limits. The pinned console fb, mob cursors and graphical login

manager tend to run out of 16MB graphics memory that those guests use.

Fix it by making sure the coherent dumb buffers are only used on

configs with 3d enabled.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
