This issue impacts nearly all current Linux systems, while versions of the Linux kernel release 4.9 or later being the most susceptible. Release version 4.8 and older, while still impacted, require more malicious traffic to exhibit the same level of resource exhaustion.
feedback from the TO team on patching the kernel is highly sought/appreciated
