Description of problem:
The /usr/share/audit/sample-rules/30-ospp-v42.rules file has section
-
- Use of special rights for config changes. This would be use of setuid
- programs that relate to user accts. This is not all setuid apps because
- requirements are only for ones that affect system configuration.
A binary which meets this criteria but is not listed is /usr/sbin/grub2-set-bootflag.
Version-Release number of selected component (if applicable):
audit-3.0.7-101.el9_0.2.x86_64
How reproducible:
Deterministic.
Steps to Reproduce:
1. cp /usr/share/audit/sample-rules/30-ospp-v42.rules /etc/audit/rules.d/
2. augenrules --load
3. As unprivileged user, run grub2-set-bootflag boot_success
4. grep grub2-set-bootflag /var/log/audit/audit.log
Actual results:
No record found.
Expected results:
