Description
In the Linux kernel, the following vulnerability has been resolved:
drm/virtio: Ensure that objs is not NULL in virtio_gpu_array_put_free()
If virtio_gpu_object_shmem_init() fails (e.g. due to fault injection, as it
happened in the bug report by syzbot), virtio_gpu_array_put_free() could be
called with objs equal to NULL.
Ensure that objs is not NULL in virtio_gpu_array_put_free(), or otherwise
return from the function.
