Seems like a really serious vulnerability, any container attack or malicious image could take over a container host if there’s no hardening on the containers.
What are runc, buildkit, moby and docker desktop? Are these tools part of a normal docker setup on linux?
Yes, the runc vulnerability affects both docker cli and podman cli.
Docker and Kubernetes use containerd, and Podman uses runc directly.

Do not run any untrusted images until the vulnerability is fixed, especially not as root.
Docker Desktop won’t really affect you as a Linux user, but moby/buildkit serves as the basis for “docker build” when building docker images. Runc is one of the base packages used for the software and so this will affect nearly all users of Docker until it gets resolved.
