Mitigation checklist
- Prevent the nfnetlink_log kernel module from being loaded by creating a configuration file: # echo "install nfnetlink_log /bin/true" > /etc/modprobe.d/disable-nfnetlink_log.conf If the module is currently loaded, attempt to unload it: # modprobe -r nfnetlink_log Caveats: If the module is in use, unloading it dynamically will fail, and a system reboot will be required for the configuration to take effect. Disabling nfnetlink_log prevents netfilter from logging packets via this netlink interface.
