Remedy

This flaw can be mitigated by preventing the affected transparent inter-process communication (TIPC) protocol kernel module from loading during the boot time. Ensure the module is added into the blacklist file. ~~~ Refer: How do I blacklist a kernel module to prevent it from loading automatically? https://access.redhat.com/solutions/41278 ~~~
