From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Dang that's scary. The user would need ssh access to the container for this to work, right?
Even worse than that, they need to be able to make an arbitrary container from an arbitrary attacker-provided Dockerfile, or make fairly arbitrary calls to the Docker daemon (in which case you've already lost).
They're rather uninteresting for anyone self-hosting containers as the runc vuln doesn't offer a way to escape from within an already running container, while the BuildKit vulns all have fairly odd preconditions or require passing untrusted input. Quite the annoyance if you're running some kind of public cloud or public CI/CD service, though.
