Nanos – A Unikernel
I can speak to this. Containers, and by extension k8s, break a well known security boundary that has existed for a very long time - whether you are using a real (hardware) server or a virtual machine on the cloud if you pop that instance/server generally speaking you only have access to that server. Yeh, you might find a db config with connection details if you landed on say a web app host but in general you still have to work to start popping the next N servers.
That's not the case when you are running in k8s and the last container breakout was just announced ~1 month ago: https://github.com/opencontainers/runc/security/advisories/G... .
At the end of the day it is simply not a security boundary. It can solve other problems but not security ones.
- Several container breakouts due to internally leaked fds
- Container breakout through process.cwd trickery and leaked fds

US Cybersecurity: The Urgent Need for Memory Safety in Software Products
It's interesting that, in light of things like this, you still see large software companies adding support for new components written in non-memory safe languages (e.g. C)
As an example Red Hat OpenShift added support for crun(https://github.com/containers/crun) this year(https://cloud.redhat.com/blog/whats-new-in-red-hat-openshift...), which is written in C as an alternative to runc, which is written in Go(https://github.com/opencontainers/runc)...

Rabbit hole indeed. That wasn't related to my job at the time, lol. The job change came with a company-provided computer and that put an end to the tinkering.

Crun: Fast and lightweight OCI runtime and C library for running containers
being the main author of crun, I can clarify that statement: I am not a fan of Go _for this particular use case_.
Using C instead of Go avoided a bunch of the workarounds that exists in runc to workaround the Go runtime, e.g. https://github.com/opencontainers/runc/blob/main/libcontaine...

Bringing Memory Safety to sudo and su - with Ferrous Systems and Tweedegolf
Not OP, but if I had to guess, a lot of this can be picked up by just observing common security issues in the Linux space, since similar mistakes and oversights have caused quite a few real-world CVEs in the past, e.g. this random example of a TOCTTOU vulnerability in runc.
