Interestingly, Ubuntu Priority is set to "High" and not "Critical" which is defined as:

"A significant problem, typically exploitable for nearly all users in a default installation of Ubuntu. Includes serious remote denial of service, local root privilege escalations, local data theft, and data loss."

The listed kernels are in the "proposed" component (and not yet in "security" or "udpates") if you want to pull them down onto canary systems for testing before going to production.

so just block multipath and add the firewall rule from article that drops packets with IPv4 options
