Shelly 2.3 GUI Package Manager for Arch Linux Brings Performance Improvements

Six-Year-Old Linux Kernel Flaw Lets Unprivileged Users Read Root-Owned Files

A proof-of-concept is available as ssh-keysign-pwn, taking advantage of the __ptrace_may_access() function in the Linux kernel, skipping the dumpable check when task->mm == NULL. As such, do_exit() runs exit_mm() before exit_files() (no mm, fds still there) and pidfd_getfd(2) succeeds in that window when the caller’s uid matches the target’s.

Ubuntu 25.10 Users Can Now Upgrade to Ubuntu 26.04 LTS, Here’s How

Ubuntu 26.04 LTS was released on April 23rd, 2026, but the upgrade path wasn’t open until now, not for Ubuntu 25.10 users and not for Ubuntu 24.04 LTS users. Of course, you can always force the upgrade with the update-manager -d command, but I wouldn’t recommend doing so as you might end up with a broken system.

KDE Plasma 6.7 Desktop Environment Is Now Available for Public Beta Testing

Fragnesia Is Yet Another Local Privilege Escalation Flaw in Linux Kernel

Fragnesia (CVE-2026-46300) is a bug in the IPsec XFRM ESP-in-TCP subsystem, part of the Dirty Frag vulnerability class. It’s called Fragnesia because the skb “forgets” that a frag is shared during coalescing. The good news this time is that the mitigations for Dirty Frag also apply to Fragnesia.

There is no digital sovereignty without ODF

posted by Rianne Schestowitz on May 16, 2026

Quoting: There is no digital sovereignty without ODF - TDF Community Blog —

ODF – Open Document Format, as the name says – was designed and developed in accordance with the characteristics of a true open standard: clearly documented, transparently developed by an independent body, properly versioned, built on existing standards, and stored in XML files that any user can read.

None of this applies to OOXML. The name is itself an oxymoron: XML stands for eXtended Markup Language, which is open by definition, but OOXML’s syntax is so complex that it is unreadable even to advanced users. The format was deliberately designed to become a sophisticated lock-in tool at a moment when Microsoft’s other strategies had already been uncovered and analysed.
