REDHAT-BUG-1427472
First published: Tue Feb 28 2017(Updated: )
Virgil 3d project, used by Quick Emulator(Qemu) to implement 3D GPU support for the virtio GPU, is vulnerable to memory leakage issue. It could occur when a guest tries to create vertex elements via 'VIRGL_OBJECT_VERTEX_ELEMENTS' command. A guest user/process could use this flaw to leak host memory resulting in DoS.
