Public bug reported:

== Impact ==

Ubuntu 22.04.5 LTS (Jammy Jellyfish)

After upgrading from kernel 5.15.0-140 to 5.15.0-160 we have multiple
issues with auditd rules.

Not fixed in 5.15.0-160-generic #170 from proposed repositories.

With large auditd.rules augenrules --load allways fail after parsing 135
lines of audit.d rules, no matter what rules we use:

There was an error in line 135 of /etc/audit/audit.rules

== Testcase ==
Loading many auditd rules (150+, I can provide the .rules file to you for 
testing) with /sbin/augenrules --load does not work as expected.

== Regression Potential ==
