The bug can be triggered by an unprivileged local user and can result in invalid data being processed by the AppArmor DFA policy engine."

El error puede ser activado por un usuario local no privilegiado y puede resultar en que datos inválidos sean procesados por el motor de políticas DFA de AppArmor."
