Timing Flaw in systemd Cleanup Enables Root Privilege Escalation

Yet another critical vulnerability in systemd, this time involving snapd. Ubuntu folk are affected. “A serious security issue has been discovered in Ubuntu, and it is gaining attention in the cybersecurity community. The vulnerability is identified as CVE-2026-3888 and mainly affects Ubuntu Desktop systems from version 24.04 onwards. This flaw is dangerous because it allows an attacker with limited access to gain full root privileges. Root access means complete control over the entire system.”

Yet another critical vulnerability in systemd This is a critical vulnerability in snapd, not systemd. It sounds like it could also be exploited if something other than systemd deleted the files in /tmp/. Or if /tmp/ was not mounted.

Yet another critical vulnerability in the much vaunted systemd has been exposed by a misbehaving app - in this case snapd. Both need patching.

Nothing in the Qualys report nor the Ubuntu page for the CVE indicate that there is something to be fixed in systemd, only that you can create systemd-tmpfiles rules that will expose the vulnerability in snapd. What do you think systemd-tmpfiles needs to do differently?

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.
