CVE-2020-36788

In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: avoid a use-after-free when BO init fails nouveau_bo_init() is
backed by ttm_bo_init() and ferries its return code back to the caller. On
failures, ttm_bo_init() invokes the provided destructor which should
de-initialize and free the memory. Thus, when nouveau_bo_init() returns an
error the gem object has already been released and the memory freed by
nouveau_bo_del_ttm().
