Linux Kernel contains an unspecified vulnerability that can allow for privilege escalation via IPv6 networking subsystem.

## Steps
1. This touches infrastructure (linux). Look in terraform, ansible, cloud-init, Dockerfiles and docs for the product and version we run. If it isn't in the repo, say so and list what a human should check on the box.

## Report
A table: file, product or package, version in use, affected yes/no, exact fix. Then anything a human has to check outside the repo.
