Over on the OpenMandriva forum, the Linux distribution has reported sabotage of its repositories by a disgruntled contributor with administrative credentials. According to "AngryPenguin", an abusive incident in a distribution Matrix chat led to a user being kicked out of the chat; that "triggered a cascade of events", which led to people resigning from the distribution. Eventually, one of those people used their administrative privileges to delete part of the distribution's GitHub repository and to "publish an empty package in the cooker repository, which obsoleted all gnome and cosmic packages, which could have damaged the systems of people using gnome or cosmic".

We are currently working to restore the deleted repositories and restore the functionality of the obsolete packages.

[...] We performed a full system audit and, aside from the removed packages, we found no other violations.

At the 2026 Linux Security Summit North America, Eric Biggers spoke about some of the problems with the kernel's cryptography framework, as well as the recent progress in adding library APIs to allow developers to use cryptographic functions without using the traditional crypto API. He walked through a couple of examples to demonstrate the frailty of the original API and showed how the new library API made life easier for developers and kernel maintainers.
