In the Linux kernel, the following vulnerability has been resolved:

drm/virtio: fix object leaks in virtio gpu resource create blob ioctl()

virtio gpu resource create blob ioctl() calls drm gem object release() on both the virtio gpu resource assign uuid() and drm gem handle create() error paths instead of dropping the reference it owns, so obj->funcs->free() never runs and the virtio gpu object, the resource id and the host-side resource are leaked.

Use drm gem object put() instead.
