Description Prasad Pandit 2017-01-24 07:25:10 UTC
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 decode context via 'VIRTIO_GPU_CMD_CTX_CREATE' command.

A guest user/process could use this flaw to leak host memory resulting in DoS.
