CVE-2022-50454

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: fix a use-after-free in nouveau_gem_prime_import_sg_table() nouveau_bo_init() is backed by ttm_bo_init() and ferries its return code back to the caller. On failures, ttm will call nouveau_bo_del_ttm() and free the memory.Thus, when nouveau_bo_init() returns an error, the gem object has already been released. Then the call to nouveau_bo_ref() will use the freed "nvbo->bo" and lead to a use-after-free bug. We should delete the call to nouveau_bo_ref() to avoid the use-after-free.
