Subject: CVE request virglrenderer: host memory leak issue in
 virgl_resource_attach_backing 

   Hello,

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 invokes a 'VIRTIO_GPU_CMD_RESOURCE_ATTACH_BACKING' command.

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