I just found this article on polkit having a CVE:

https://github.blog/2021-06-10-privilege-escalation-polkit-root-on-linux-with-bug/ (https://github.blog/2021-06-10-privilege-escalation-polkit-root-on-linux-with-bug/)
It looks pretty nasty...

" The vulnerability enables an unprivileged local user to get a root shell on the system. It’s easy to exploit with a few standard command line tools, as you can see in this short video (https://youtu.be/QZhz64yEd0g). In this blog post, I’ll explain how the exploit works and show you where the bug was in the source code. "
In the hacker news comments it is fixed in:
https://news.ycombinator.com/item?id=27462247 (https://news.ycombinator.com/item?id=27462247)

Polkit version 0.119 fixes it, here's the diff: https://gitlab.freedesktop.org/polkit/polkit/-/commit/a04d13... (https://gitlab.freedesktop.org/polkit/polkit/-/commit/a04d13affe0fa53ff618e07aa8f57f4c0e3b9b81)
You all awesome devs have probably already fixed it, but I am just emailing to make sure.

Thanks!

It was fixed in Guix[0], but thank you for your vigilance! o7

Guix commit 9178566954cc7f34d2d991d31df4565adad93508 ought to fix this
with a patch and graft.  If you haven't updated already, consider doing
so.  If you want to play with polkit, you can always roll back :P
