Overview
About vulnerability
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.
