## Description

In the Linux kernel, the following vulnerability has been resolved:  apparmor: fail policy unpack on accept2 allocation failure  unpack_pdb() may need to allocate a missing ACCEPT2 table for older policy data. If that allocation failed, it set an error message but jumped to the success path, returning a policydb with the required table missing.  Return -ENOMEM through the normal failure path when the ACCEPT2 allocation fails. Remove the now-unused out label.
