✅ 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 do not 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 `rxe` kernel module from loading. This can be achieved by creating a blacklist rule. 1. Create a file `/etc/modprobe.d/blacklist-rxe.conf` with the following content: ``` blacklist rxe install rxe /bin/true ``` 2. Rebuild the initial ramdisk: ```bash dracut -f -v ``` 3. Reboot the system for the changes to take effect. Warning: Blacklisting the `rxe` module may impact functionality that relies on Soft RoCE. 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.
