✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. Workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Workaround: To mitigate this issue, prevent the `bonding` kernel module from loading if bonding interfaces are not required. This can be achieved by creating a modprobe configuration file. Create a file named `/etc/modprobe.d/disable-bonding.conf` with the following content: `install bonding /bin/true` After creating the file, a system reboot is required for the change to take effect if the module is currently loaded. This action will prevent the creation and use of bonding network interfaces. Workaround: To mitigate this issue, prevent module iscsi_target_mod from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically. Workaround: To mitigate this issue, prevent module macvlan from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
