RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description kat 2018-02-21 18:12:40 UTC 
Description of problem:

Rule with this ID does not remediate properly
Always fails this SCAP test, even after applying remediation script. 

test ID:
xccdf_org.ssgproject.content_rule_audit_rules_kernel_module_loading

We used the redhat-provided remediation script for this rule, which generated the following rules file:

# cat /etc/audit/rules.d/modules.rules 
-a always,exit -F arch=b64 -S init_module -S delete_module -k modules
-w /usr/sbin/insmod -p x -k modules
-w /usr/sbin/rmmod -p x -k modules
-w /usr/sbin/modprobe -p x -k modules

Version-Release number of selected component (if applicable):

scap-security-guide-0.1.33-6.el7_4.noarch
Comment 2 Marek Haicman 2018-02-22 19:33:40 UTC 
The problem is OVAL check expects both b64 and b32 rules to be present. This is not expressed in description of the rule, nor taken into account in the remediation script. But it is correct behaviour. Thus if you want to pass, you need to add another line catching b32 into /etc/audit/rules.d/modules.rules. Containing this, rule will pass:

-a always,exit -F arch=b32 -S init_module -S delete_module -k modules
-a always,exit -F arch=b64 -S init_module -S delete_module -k modules
-w /usr/sbin/insmod -p x -k modules
-w /usr/sbin/rmmod -p x -k modules
-w /usr/sbin/modprobe -p x -k modules
