-Subject: [PATCH 2/8] display: virtio-gpu-3d: check virgl capabilities max_size
-
-Virtio GPU device while processing 'VIRTIO_GPU_CMD_GET_CAPSET'
-command, retrieves the maximum capabilities size to fill in the
-response object. It continues to fill in capabilities even if
-retrieved 'max_size' is zero(0), thus resulting in OOB access.
-Add check to avoid it.
