Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/vmwgfx: Disable coherent dumb buffers without 3d<br /> <br /> Coherent surfaces make only sense if the host renders to them using<br /> accelerated apis. Without 3d the entire content of dumb buffers stays<br /> in the guest making all of the extra work they&amp;#39;re doing to synchronize<br /> between guest and host useless.<br /> <br /> Configurations without 3d also tend to run with very low graphics<br /> memory limits. The pinned console fb, mob cursors and graphical login<br /> manager tend to run out of 16MB graphics memory that those guests use.<br /> <br /> Fix it by making sure the coherent dumb buffers are only used on<br /> configs with 3d enabled.
