[Bug 2040250] Re: apparmor notification files verification

This bug is awaiting verification that the linux-gke/6.8.0-1004.7 kernel
in -proposed solves the problem. Please test the kernel and update this
bug with the results. If the problem is solved, change the tag
'verification-needed-noble-linux-gke' to 'verification-done-noble-linux-
gke'. If the problem still exists, change the tag 'verification-needed-
noble-linux-gke' to 'verification-failed-noble-linux-gke'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
apparmor notification files verification

Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Mantic:
Fix Committed

Bug description:
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.
