    Mitigation guidance
    • If QLogic Fibre Channel HBAs are not in use, the 'qla2xxx' kernel module can be blacklisted to prevent it from loading. This can be achieved by creating a modprobe configuration file. To blacklist the module: 1. Create a file named `/etc/modprobe.d/blacklist-qla2xxx.conf` with the following content: `blacklist qla2xxx` 2. Regenerate the initramfs to ensure the blacklist is applied during boot: `sudo dracut -f -v` (for RHEL 7/8/9) `sudo mkinitcpio -P` (for Arch-based systems, if applicable) 3. Reboot the system for the changes to take effect. Warning: Blacklisting this module will disable functionality for QLogic Fibre Channel HBAs. Ensure that this hardware is not required before applying this mitigation. A system reboot is required for the changes to take effect.
