## Overview

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

drm/virtio: release the GEM object on virtio_gpu_vram_create() errors

virtio_gpu_vram_create() frees the object with a bare kfree(vram) on
both error paths after drm_gem_private_object_init() has run, and on the
second one after drm_gem_create_mmap_offset() has linked obj->vma_node
into the device's VMA offset manager. The freed object stays in that
interval tree, so a later lookup or insertion walks freed memory, and
the dma_resv and gpuva lock are never destroyed.

Call drm_gem_object_release() before kfree() on both paths.
