The XanMod kernel offers improved performance with its block-layer runqueue tweaks and revamped scheduler, resulting in smoother multitasking. It also includes aggressive x86_64 optimizations from LLVM's ThinLTO for better I/O boosts. For low-latency workloads like audio production, robotics, or gaming, the linux-xanmod-rt package is available, which ships a PREEMPT_RT-enabled kernel based on 6.18 with deterministic scheduling. The XanMod kernel is compatible with various drivers, including NVIDIA and VirtualBox, although some may require reinstalling under new headers to work properly.
Several security issues have been fixed in various packages, including expat, libxmltok, and Linux kernel, which affect Ubuntu 24.04 LTS, 22.04 LTS, 20.04 LTS, 18.04 LTS, 16.04 LTS, and 14.04 LTS. The updates fix vulnerabilities that could potentially allow an attacker to cause a denial of service or execute arbitrary code, including issues related to memory handling, integer calculations, and external entity initialization. To address these issues, users are advised to update their systems to the latest package versions, which can be done by running a standard system update. The affected packages include expat 2.7.1-2ubuntu0.2, libxmltok1 1.2-4ubuntu0.22.04.1~esm6, and Linux kernel version 6.8.0-100.100.

Liquorix Kerne 6.18‑10 has just been released, merging the Linux Kernel 6.18.9 sources and bumping the package version to 6.18.9‑1. The kernel is tuned for extreme responsiveness in interactive desktops, low‑latency A/V production, and reduced frame‑time jitter in games, using features such as Zen Interactive Tuning, a 1000 Hz tick rate, and aggressive preemption. The project supplies Debian packages and Docker‑based build scripts that require Docker and a configured GnuPG key; at present only the AMD64 architecture can be built successfully for Debian, Ubuntu and Arch targets.
The XanMod kernel has released two new versions: 6.18.9 and the long-term 6.12.69, which are now available for Debian/Ubuntu. The XanMod kernel series includes features such as LLVM's ThinLTO and aggressive scheduling, making it suitable for low-latency audio workstations or gaming rigs.
Ubuntu has released security notices for several vulnerabilities, including Linux kernel vulnerabilities (USN-7988-3), GLib library vulnerabilities (USN-8017-1), and Python programming language vulnerabilities (USN-8018-1). The Linux kernel vulnerabilities affect Ubuntu 18.04 LTS, 16.04 LTS, and 14.04 LTS, and can be corrected by updating the system to new package versions. The GLib library vulnerabilities affect Ubuntu 25.10, 24.04 LTS, and 22.04 LTS, and can also be corrected by updating the system to new package versions. Additionally, tracker-miners was found vulnerable in Ubuntu 25.10, 24.04 LTS, and 22.04 LTS, and requires a session restart after update to correct the issue.

Ubuntu Linux 26.04 Snapshot 3 has been released for testing, marking another significant step in the development process. These snapshots are early-stage builds, meant for temporary testing and not suitable for serious use yet. The next snapshot, Ubuntu 26.04 Snapshot 4, is scheduled to be released on February 26th, giving developers a deadline to upload their changes. The steady pace of development brings new features closer to reality, inching the community towards a solid LTS release due in April 2031.
The new Liquorix Kernel 6.18-9, based on Kernel 6.18.8, has been released, promising a snappier desktop experience with lower frame-time jitter in games and smoother video work. The kernel sacrifices some power efficiency for improved interactivity, making it suitable for users who spend more time in browsers or games rather than spreadsheets. To install the new kernel safely, users can run a provided script that pulls pre-built packages and updates GRUB, allowing them to verify the new entry before rebooting into "hyper-responsive" mode. The kernel includes various changes under the hood, including scheduler tweaks, memory reclamation, CPUFreq adjustments, and more aggressive preemptive handling of interactive tasks.
The Linux kernel has been updated to fix several security issues that could be exploited by an attacker. The vulnerabilities were discovered in the Cryptographic API, Padata parallel execution mechanism, and Netfilter subsystems. This update affects various Ubuntu releases, including 20.04 LTS and 18.04 LTS. To fix these issues, users need to update their system to the latest kernel versions and reboot their computer.

XanMod 6.18.8 brings LLVM ThinLTO, BBRv3 and an optional PREEMPT_RT build to Debian‑based machines, delivering noticeably smoother I/O and scheduler performance on everyday hardware. This step‑by‑step guide shows how to add the repository, import the signing key, install the kernel and pull in just the DKMS toolchain you actually need. It also warns about the most common module breakages – NVIDIA, VirtualBox and older NVIDIA drivers – and gives quick fixes that saved me from a black screen. Keep a fallback kernel handy, reboot, and verify with uname -r to make sure you’re running the new 6.18.8‑xanmod1 kernel.

A new version of the XanMod kernel for Debian and Ubuntu has been released. This kernel adds LLVM ThinLTO, aggressive x86_64 scheduling and networking upgrades like BBRv3 that can noticeably speed heavy I/O or compilation workloads. The kernel may break DKMS‑based drivers (NVIDIA, OpenZFS, VirtualBox/VMware), so keep the old kernel handy and be ready to reinstall or revert if needed. Install it by adding the XanMod repo, pulling in linux-xanmod and its headers, then rebooting and selecting the new entry.
Liquorix Kernel 6.18‑8 swaps the default scheduler for Kyber/BFQ, tightens CPU timeslices to 2 ms and enables aggressive preemption, giving desktops a noticeably snappier feel at the cost of a bit more power draw. The one‑liner install script simply adds the Liquirx repo, pulls the proper .deb (or AUR) package and updates GRUB—just save the script first, glance at it, then run it with sudo. Expect minor side effects like higher fan speed on laptops, possible firmware or driver rebuilds for older GPUs/NVIDIA cards, and a small learning curve if you use systemd‑boot instead of GRUB
