Sounds like the crash is resolved and now you're getting a denial from a security module. I looked in the code, it looks like AppArmor doesn't register any callbacks for the ib_* security hooks, and if no hook is registered it should return 0. Can you tell me more about your setup so I can create a reproducer? What OS are you using? Can you double check that SELinux isn't enabled (see output of sestatus).
