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.

Fork time? Maybe all the anti-systemd zealots were right all along...

Edit: To address whether it is likely that this change will affect users: Gnome is planning a stronger dependence on userdb, the part of systemd where this change is being implemented. https://blogs.gnome.org/adrianvovk/2025/06/10/gnome-systemd-dependencies/

Final Edit: The PR has been merged into main.

Unfortunate. However, it seems that is snapd's fault. Here's the important part from the article:

Ubuntu automatically deletes old files from the /tmp directory after a certain number of days. During this cleanup, an important directory used by snap-confine may get removed.

Ubuntu configured systemd-tmpfiles to clean out /tmp after some days. That's why the issue is only present in Ubuntu systems. Therefore, systemd was doing it's job, and it just so happened to create the perfect conditions for a vulnerability in Ubuntu.
