CURL, Kernel, Python-Cryptography, Roundcube for Ubuntu

Ubuntu 7041 Published 2026-03-17 06:50 by Philipp Esselbach 0

Ubuntu released several security advisoriesto patch kernel vulnerabilities affecting AppArmor modules and numerous subsystems across multiple LTS releases. Affected systems require a system reboot following installation because these fixes address critical flaws allowing unprivileged users to escape containers or leak sensitive memory. One advisory reverses a regression in python-cryptography while another fixes cross-site scripting risks found in the Roundcube Webmail interface for multiple Ubuntu versions. Finally, older distributions must upgrade the curl package to prevent credential reuse issues during authentication processes for HTTPS requests.

Linux kernel updates for Ubuntu

Ubuntu 7041 Published 2026-03-17 06:46 by Philipp Esselbach 0

Three separate Ubuntu security notices were published to fix critical vulnerabilities in the Linux Kernel. These updates address hardware drivers and file systems for both newer editions alongside older long term support releases. Security researchers identified that unprivileged local attackers could exploit the AppArmor Linux kernel Security Module to potentially gain elevated privileges or access sensitive data on affected systems. System administrators must update their package versions immediately and reboot because an unavoidable ABI change requires recompiling third party kernel modules you might have installed previously.

XanMod Kernel 6.19.7 and 6.18.17: How to Install, What Drivers Need Updating, and When the Default Debian Kernel Still Wins

Debian 10851 Ubuntu 7041 Published 2026-03-12 17:37 by Philipp Esselbach 0

XanMod has released kernel versions 6.19.7 and 6.18.17, built with LLVM ThinLTO and enhanced scheduling that can lower CPU usage and improve latency for heavy workloads. Installing the kernel is as easy as adding a signed repository line to APT, updating the package list, and running sudo apt install linux-xanmod-x64v3. Users with NVIDIA, OpenZFS, VirtualBox, or VMware modules should verify driver compatibility first, since some proprietary modules lag behind the new thinlto patches and can cause panics. For those who need guaranteed support for cutting‑edge hardware or legacy systems, the distribution’s stock kernel remains a reliable fallback.

Liquorix Kernel 6.18-19 Release: Improved Performance and Efficiency for Linux Users

Debian 10851 Ubuntu 7041 Arch Linux 949 Published 2026-03-05 07:59 by Philipp Esselbach 0

The latest release of Liquorix Kernel, version 6.18-19, has been made available for Debian, Ubuntu, and Arch Linux distributions, offering improved performance and efficiency through tweaks like Kyber and BFQ schedulers. These changes result in faster UI wake-ups when copying large files or rendering video frames, as well as snappier mouse movement and lower frame-time jitter in fast-paced games. While Liquorix may not be necessary for users with office boxes that rarely leave the desk, those who engage in competitive gaming or audio/video production are likely to notice a significant difference. To install Liquorix on any of these distributions, simply run an installation script provided by the project, which will automatically add the repository and update GRUB.

Upgrade to XanMod Kernels: Boost Linux Performance with Optimized 6.19.6 and 6.18.16 LTS Releases

Debian 10851 Ubuntu 7041 Published 2026-03-05 07:42 by Philipp Esselbach 0

XanMod has released two new kernels, 6.19.6 and 6.18.16 LTS, which offer significant performance improvements for tasks like number crunching and high-resolution video streaming. To install these kernels on Debian or Ubuntu systems, you'll need to add a PGP key and register the XanMod repository; this process involves running two commands in the terminal. After installing the kernel, be sure to reboot your system and verify that it's working correctly by checking the version number in /proc/version; if everything went smoothly, the output should contain "xanmod" followed by the exact version number. Upgrading to XanMod kernels can provide noticeable speed and responsiveness gains for desktops and servers alike, making them a worthwhile upgrade for anyone looking to boost their system's performance.

Mailman and Git updates for Ubuntu

Ubuntu 7041 Published 2026-03-03 07:18 by Philipp Esselbach 0

Ubuntu has issued security notices for vulnerabilities in Mailman and Git. A vulnerability in Mailman, discovered in 2021, allowed remote list members or moderators to potentially set new admin passwords or make other changes, which has been fixed by updating to version 1:2.1.29-1ubuntu3.1+esm2 on Ubuntu 20.04 LTS and version 1:2.1.20-1ubuntu0.6+esm3 on Ubuntu 16.04 LTS. Another notice addressed a regression in Git introduced by a previous update, which allowed an attacker to run arbitrary commands; this has been fixed by updating to version 1:2.17.1-1ubuntu0.18+esm8 on Ubuntu 18.04 LTS. These updates are available through a standard system update and can also be found with Ubuntu Pro

Liquorix Kernel 6.18-17: Boosting Responsiveness and Gaming Performance

Debian 10851 Ubuntu 7041 Arch Linux 949 Published 2026-03-01 08:09 by Philipp Esselbach 0

The new Liquorix Kernel 6.18-17 brings together the upstream Linux 6.18.15 tree with tweaks aimed at improving responsiveness and gaming performance, while sacrificing some throughput and power efficiency. This community-maintained kernel keeps classic Zen patches and adds preemptible RCU implementation, resulting in faster mouse clicks, smoother video rendering, and steadier game frames under mixed workloads. The release also includes key tuning changes such as shrinking scheduling timeslice to 2 ms, adjusting CPU-frequency governor settings, and enabling background hugepage reclamation. For those looking for low jitter and fast wake-ups, Liquorix Kernel 6.18-17 is a solid choice, but users prioritizing battery life or stability under exotic hardware may want to stick with the distro kernel.

Install XanMod Kernel 6.8.15 on Debian or Ubuntu: A Step-by-Step Guide

Debian 10851 Ubuntu 7041 Published 2026-03-01 08:01 by Philipp Esselbach 0

The XanMod kernel release 6.8.15 brings several improvements, including ThinLTO, better block I/O handling, and a built-in BBRv3 TCP congestion controller. To get this new kernel running on Debian or Ubuntu while keeping graphics working, you need to trust the upstream signing key and add the XanMod repository to your system. The process involves updating the package index, installing the main XanMod package, and installing any required external modules or drivers like NVIDIA. After installation, a quick sanity check can be performed by reading /proc/version to confirm that the new kernel is running, and troubleshooting may involve verifying GRUB's default entry and rebuilding custom packages like OpenZFS DKMS.
