✅ 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. Red Hat recommends treating all kernel errata as security-relevant. Given the kernel's fundamental role, any bug has a higher chance of impacting system security, even if that impact only becomes clear after a fix is published. Therefore, Red Hat prioritizes delivering fixes that improve our customers' overall security posture. Because of this proactive approach, a patch may be associated with a CVE assignment at a future date. Retroactive CVE assignments are always documented in the corresponding errata and on Red Hat's CVE pages. We strongly advise against delaying updates, as doing so may leave your system exposed when protections are already available. Workaround: To mitigate this issue, if the `qla2xxx` SCSI driver is not required, it can be prevented from loading by blacklisting the module. This can be achieved by creating a modprobe configuration file. 1. Create a file named `/etc/modprobe.d/blacklist-qla2xxx.conf` with the following content: ``` blacklist qla2xxx install qla2xxx /bin/true ``` 2. Rebuild the initial ramdisk: ```bash dracut -f -v ``` 3. Reboot the system for the changes to take effect. This mitigation will prevent the `qla2xxx` module from loading, which may impact systems relying on QLogic Fibre Channel HBAs. A system reboot is required for the changes to take full effect. Workaround: To mitigate this issue, prevent module sctp 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: 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, disable the Wi-Fi functionality if it is not required. This can be done by blacklisting the `cfg80211` kernel module. 1. Create a new file `/etc/modprobe.d/disable-wifi.conf` with the following content: ``` blacklist cfg80211 ``` 2. Rebuild the initial ramdisk: ```bash sudo dracut -f -v ``` 3. Reboot the system for the changes to take effect. This mitigation will prevent the `cfg80211` module, and thus Wi-Fi, from loading. This may impact network connectivity if Wi-Fi is the primary or only network interface.
