Title
apparmor: fix possible NULL pointer dereference
Summary
In the Linux kernel, the following vulnerability has been resolved: apparmor: fix possible NULL pointer dereference profile->parent->dents[AAFS_PROF_DIR] could be NULL only if its parent is made from __create_missing_ancestors(..) and 'ent->old' is NULL in aa_replace_profiles(..). In that case, it must return an error code and the code, -ENOENT represents its state that the path of its parent is not existed yet.
