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

Some of the highlights of KDE Plasma 6.7 include per-screen virtual desktops, Wayland session restore, a global push-to-talk feature, a dedicated setup UI for configuring shared printers, a “multi-GPU swapchain” feature for Vulkan support, and a full-featured print queue viewer app.

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.

PipeWire 1.6.5 Brings Extra Security Checks and Hardening Fixes to Pulse Server

Coming three weeks after PipeWire 1.6.4, the PipeWire 1.6.5 release is here to add a whole bunch of extra security checks and hardening fixes to the pipewire-pulse server, improve renegotiation in audioconvert when the graph rate changes and the resampler is disabled, and fix a crash in ALSA when logging.

KDE Receives Over €1M from Sovereign Tech Fund for Software Development

The Sovereign Tech Agency is well known for funding open source projects through its Sovereign Tech Fund program, and it provided over €24.6 million EUR in funding to support more than 60 open source projects globally, including big names like Python Software Foundation, FreeBSD, Eclipse Foundation, OpenStreetMap Foundation (OSMF), and Drupal.

How RightsCon Is an Unexpected Stress Test for the Multistakeholder Model of Internet Governance

The cancellation of RightsCon 2026 is a stark reminder that when opportunities for civic engagement are neutralized, so are stakeholders’ voices. In this case, civil society was denied the ability to meet in person in Lusaka last week to share ideas and opportunities for how to address some of the most urgent digital challenges of our time.

CachyOS ISO Release for April 2026 Brings Shelly as Default GUI Package Manager

posted by Marius Nestor on Apr 26, 2026,
updated May 04, 2026

Powered by the long-term supported Linux 6.18 LTS kernel series, the CachyOS ISO snapshot for April 2026 ships with the latest and greatest KDE Plasma 6.6.4 desktop environment by default, which is accompanied by the KDE Frameworks 6.25 and KDE Gear 26.04 software suites.

However, the biggest change in the new CachyOS ISO release is that the devs decided to adopt Zoey Bauer’s Shelly as the new default graphical package manager, replacing Octopi. Shelly supports installation of packages from AUR, Flathub, FlatpakRef, AppImage, and local source files.

CachyOS April 2026 Release

This is our third release of the year, bringing a new default GUI package manager, DNS-over-HTTPS support, fingerprint-based sudo, and a variety of installer and hardware detection improvements!

First, the installer now ships Shelly as the GUI package manager, replacing Octopi. A clean snapshot is now created immediately after the installation has finished and is retained permanently, providing users with a reliable baseline restore point. GRUB os-prober is now enabled by default to detect other operating systems on the same machine. The UKUI desktop has been dropped from the selection, and the GNOME package selection has been cleaned up and modernised. For AMD GPUs, a different Plymouth theme is now used, as the amdgpu driver was unable to render the previous theme reliably on laptops with a secondary monitor attached. Last but not least, a new option was introduced in the installer that sets up MangoWM with DMS shell.
