Public bug reported:
apparmor notifications on the 6.5 kernel are failing verification
between the header size and the returned size.
When strings are appended to the notification the header size should
be updated to reflect the correct size. While the size is also
directly returned as part of delivering the notification, the header
should also be update to conform to specification and allow for
verification.
If verification is enabled and the notification contains appended
strings then notifications fail verification and won't be delivered.
