# Linux kernel: virtio-gpu blob ioctl leaks objects on error paths

In the Linux kernel's virtio-gpu DRM driver, error paths in the blob resource creation ioctl release GEM objects incorrectly, so the object, its resource id and the host-side resource are never freed. The effect described is a resource leak that can accumulate over time, and the sources do not describe code execution or data exposure.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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.
