==============================================
  Hello,

Virgil 3d project, used by Quick Emulator(Qemu) to implement 3D GPU support for
the virtio GPU, is vulnerable to a null pointer dereference issue. It could
occur when a guest invokes a virgl 'VIRGL_CCMD_CLEAR' command.


A guest user/process could use this flaw to crash Qemu process resulting in
DoS.
