Modern CPUs all have multiple hardware vulnerabilities that the kernel needs to mitigate; the 6.13 kernel has workarounds for 14 security-sensitive CPU bugs just on x86_64. Several of those have multiple variants, or multiple mitigations that apply on different microarchitectures. There are different kernel command-line options for each of these mitigations, which leads to a confusing situation for users trying to figure out how to configure their systems. David Kaplan recently posted a patch set that adds a single, unified command-line option for controlling mitigations and simplifies the logic for detecting, configuring, and applying them as well. If it is merged, the patch set could make it much easier for users to navigate the complicated web of CPU vulnerabilities and their mitigations.

Version 7.1 of PeerTube, a tool for sharing videos online, has been released. Notable features in this release include improved support for the Podcast 2.0 standard, better playback stability, and a new view protocol enabled by default to allow PeerTube to handle more simultaneous viewers. See the release notes for more details.

/e⁠/⁠OS is a privacy-centric, open-source mobile operating system that has primarily been targeted at mobile phones, with only a few community supported images available for tablet devices. In December, Murena—a company that sells devices with /⁠e⁠/⁠OS preinstalled—announced that /⁠e⁠/⁠OS now officially supports tablets as well, starting with the Pixel tablet. The user experience is close enough to mainstream alternatives to make it attractive, but there are some under-the-hood problems that may give users pause.

A security company called Fenrisk has posted an overview of a pair of claimed successful supply-chain attacks on the Fedora and openSUSE distributions.

We successfully identified vulnerabilities in the Pagure, the Git forge used by Fedora to store their package definitions. We also compromised Open Build Service, the all-in-one toolchain used and developed by the openSUSE project for compilation and packaging.

Their exploitation by malicious actors would have led to the compromise of all the packages of the distributions Fedora and openSUSE, as well as their downstream distributions, impacting millions of Linux servers and desktops.

Security updates have been issued by Debian (tzdata), Fedora (expat and tigervnc), Red Hat (kernel, kernel-rt, thunderbird, and webkit2gtk3), SUSE (dcmtk), and Ubuntu (restrictedpython and uriparser).

This post explains CPU load, how it affects your Linux server, and how to deal with it in critical moments. We think about high CPU usage and CPU load when discussing essential moments. These are two different things, even though they sound similar. Besides this, we will explain the CPU as the most critical part of a server. What causes high CPU utilization, different commands to check the CPU utilization, and some suggestions to prevent high usage

In other words, how to manage your CPU resources rationally so your hosted websites are free of issues. Let’s get started!

The Linux kernel is the core component of any Linux operating system, managing hardware resources and system processes.

The latest version available of the Kernel 6.14 branch is Kernel 6.14 RC6, which has been described by Linus Torvalds as a boring release.

Kernel 6.14 RC6 highlights:

• AMDXDNA Driver Introduction: The new AMDXDNA driver has been introduced to support Ryzen AI Neural Processing Units (NPUs), enhancing AI capabilities on AMD platforms.
• NTSYNC Driver Implementation: The NTSYNC driver has been implemented to emulate Windows NT synchronization primitives within the Linux kernel, potentially improving performance for Windows games running on Linux through Wine.
• Networking Enhancements: Updates include refactoring the networking core to reduce RTNL lock contention, optimizing XDP socket code, and improving ICMP rate-limiting scalability.
• Scheduler Improvements: Enhancements to the fair scheduler (SCHED_FAIR), deadline scheduler, and load-balancer have been made to improve performance and efficiency.
• Rust Language Support: The kernel now includes abstractions for developing PCI and platform device drivers using the Rust programming language, paving the way for more Rust-based drivers in the future.
• AMD CPU Feature Support: Support for new AMD CPU features, including Secure TSC and SRSO_USER_KERNEL_NO, has been added to enhance security and performance on AMD platforms.

In this guide we will be installing Kernel 6.14 RC6, which has been released a while go.

Running Windows software and games on Linux has become increasingly accessible, thanks to tools like CrossOver 25, which is developed by CodeWeavers.

CrossOver is a commercial software solution that allows Linux users to run a wide range of Windows applications without the need for a Windows operating system license.

As you may know, GIMP (GNU Image Manipulation Program) is a free and open-source image editing software used a lot on Linux systems, as a free alternative of Adobe Photoshop (that can be used hand-in-hand with Inkscape).

It is widely used by photographers, graphic designers, illustrators and digital artists, providing a set of tools for tasks like photo retouching, image composition, and graphic design. It also includes layer masking, color corection and digital painting, making the tool very powerful.

As you may already know, Darktable is a free and open-source photography workflow application for image editing (that be used hand-in-hand with GIMP) with good support for Linux, Mac OSX, Solaris and Windows. It’s main purpose is to enhance a photographer’s workflow, permitting you to manage and adjust a large number of images efficient and easy.

Darktable operates in two modes: Lighttable (which allows you to export, sort and rename images) and Darkroom (which permits editing photos and raw files). The GUI looks very similar to Lightroom Classic, so if you have used that already, you might feel at home.

elementary OS is an Ubuntu-based desktop distribution. Some of its more interesting features include a custom desktop environment called Pantheon and many custom apps including Photos, Music, Videos, Calendar, Terminal, Files, and more. It also comes with some familiar apps like the Epiphany web browser and a fork of Geary mail.

Linuxfx is a Brazilian Linux distribution based on Ubuntu. It ships with an intuitive Cinnamon desktop user interface designed to facilitate migration of users from Windows. It includes a video management system called Sentinela, a computer vision software with video analytics and software for access control (facial recognition and automatic number plate recognition), object detection, gender, age and mood detection. Other features of the distribution include a new personal assistant, a WX theme for desktop and system applications, and compatibility with software written for Windows (.exe and .msi) through a Wine port. Following the release of Linuxfx 10.6 the distribution became a commercial offering.

Fedora Linux (formerly Fedora, formerly Fedora Core) is a Linux distribution developed by the community-supported Fedora Project and owned by Red Hat. Fedora Linux contains software distributed under a free and open-source license and aims to be on the leading edge of such technologies. Fedora has a reputation for focusing on innovation, integrating new technologies early on and working closely with upstream Linux communities. The default desktop in Fedora Linux is the GNOME desktop environment and the default interface is the GNOME Shell. Other desktop environments, including KDE, Xfce, LXDE, MATE and Cinnamon, are available. The Fedora project also distributes custom variations of Fedora called Fedora spins. These are built with specific sets of software packages, offering alternative desktop environments or targeting specific interests such as gaming, security, design, scientific computing and robotics.

If all goes according to plan, the Ubuntu project will soon be replacing many of the traditional GNU utilities with implementations written in Rust, such as those created by the uutils project, which we covered in February. Wholesale replacement of core utilities at the heart of a Linux distribution is no small matter, which is why Canonical's VP of engineering, Jon Seager, has released oxidizr. It is a command-line utility that helps users easily enable or disable the Rust-based utilities to test their suitability. Seager is calling for help with testing and for users to provide feedback with their experiences ahead of a possible switch for Ubuntu 25.10, an interim release scheduled for October 2025. So far, responses from the Ubuntu community seem positive if slightly skeptical of such a major change.
