Checklist

• I agree to follow the Code of Conduct that this project adheres to.
• I have searched the issue tracker for a bug that matches the one I want to file, without success.
• If this is an issue with a particular app, I have tried filing it in the appropriate issue tracker for the app (e.g. under https://github.com/flathub/) and determined that it is an issue with Flatpak itself.
• This issue is not a report of a security vulnerability (see here if you need to report a security issue).

Flatpak version

1.16.0

What Linux distribution are you using?

Arch Linux

Linux distribution version

Rolling

What architecture are you using?

x86_64

How to reproduce

1. Use the Flatpak package of an app e.g. Rnote
2. Try to import a PDF file
3. The kernel will throw a bunch of kernel: BUG: Bad page state in process ...

Expected Behavior

This issue is not reproducible with Linux Kernel 6.12.12, but both with 6.13 and 6.13.1 on multiple devices. I guess expected behaviour would be to not crash.

Actual Behavior

Somehow, interacting with certain files in some ways can cause these crashes. I was able to reproduce this issue with the Flatpak packages of multiple apps and can also confirm, that this issue does not happen when installing another version of the package. This is one such crash, I filed the issue with this repo since the process throwing the error is not always xdg-permission-. I've also seen fuse, the app itself, kworker, or the terminal emulator when running flatpak run .... The crash is always reproducible and leads to a full system crash every time but sometimes after a while and sometimes immediately.

Additional Information

I did find this issue, but since none of my crashes mentioned xdg-desktop-portal AFAIK I wasn't sure if this is also a kernel regression, although it would make sense and I did see FUSE come up in the crash logs.

Having a similar issue, but it seems to only really happen with Bottles for me? If I try to run any executable within a bottle, nothing will really happen but within a minute the whole system will become unresponsive and then completely hang, forcing me to do a hard reset.

It still worked fine yesterday, these problems started happening today and the only two major updates I saw were the kernel and glibc, which does have some bug reports about breaking things. Might be related?

Flatpak does not control the behaviour of your kernel, and user-space code should not be able to trigger this sort of crash even if we wanted to. Please report this to your OS vendor as a kernel bug.

kernel: BUG: Bad page state in process xdg-permission-

This isn't actually Flatpak, it looks like xdg-permission-store (which is part of https://github.com/flatpak/xdg-desktop-portal, and is used/required by Flatpak but not part of the same codebase). The same reasoning applies equally to why this isn't a xdg-desktop-portal bug, though.

I started testing the Linux 6.13 kernel before the glibc bump, so in that case this definitely seems kernel related. I filed in issue on GitLab, maybe it's helpful if you add your findings there @CosmicHeron :)
