I may found one in qubes-manager.noarch 4.3.23-1.fc41
Namely, when trying to boot from ISO while creating a qube, Settings and Qube Manager windows crash. I won’t paste logs.
What helps is patching /usr/lib/python3.13/site-packages/qubesmanager/settings.py
on line 1392, and changing:
vm=self.vm.name
to
vm=self.vm
It is related to /usr/lib/python3.13/site-packages/qubesmanager/bootfromdevice.py
DISCLAIMER: I used my eyes, fingers, keyboard, mice, laptop, Qubes OS, dom0’s xfce4-terminal, AI and Calculator to asses this. And my brain.
And I am over 18.
My neighbors weren’t involved in this in any shape or form, so they are completely innocent.
If I forgot to disclose any other internal enemy, please let me know. Happy to be a snitch.

Lovely, I think this belongs on github as a bug report / issue though no?
Me no Github. Account. Also, who knows… Let’s wait for someone else to jump in…?

You don’t need to disclose AI use per se if you didn’t use it to substantially generate your post. The policy is not some purity test for maximally manual labor.
Wow, a lot of patches there unlike my one-liner?
This policy applies to every way in which you may contribute to, or interact with, the project, including (but not limited to) code, patches, packages, issue tracking, reporting security issues, documentation, artwork, discussion forums, mailing lists, social media, chat, and email.
Darn, again didn’t read it properly! Just joking @rustybird . I sincerely appreciate you and it is nothing personal. It is just that at the moment it invokes my cynicism, nothing else. It’ll pass by in a several posts… otherwise it’d get boring to repeat it, and I am aware of that.
Cheers.
Some vulnerabilities are not fatal, but rather related to user experience.
Uhm, or related to functionality?
