Liquorix Linux Kernel 7.0-18 released with Project-C scheduler fix
The latest Liquorix build, version 7.0-18, has landed. The release brings a targeted fix for the Project-C scheduler, addressing a use-after-free bug in the active balance task of the sched/alt subsystem.
If you're running the enthusiast-grade kernel for low-latency gaming or A/V production, this keeps the scheduler stable under mixed workloads. The new build continues to ride on top of Linux 7.0.14 upstream.
Liquorix remains one of the most active custom kernel projects for desktop users. It targets interactive systems where responsiveness beats raw throughput. The Project-C scheduler is the project's signature feature, replacing the standard CFS with a priority-and-deadline-based skip list structure designed for better task interleaving.
Steven Barrett, known as "damentz," maintains the project. The 7.0-18 update is a patch-level release. It doesn't bring new upstream features. Instead, it focuses on squashing bugs that could cause crashes or memory corruption during active balancing operations.
You can install the new kernel via the official script, which sets up the repository for Debian, Ubuntu, and Arch-based distros:
curl -s 'https://liquorix.net/install-liquorix.sh' | sudo bash
For what it's worth, the Liquorix kernel stays relevant by keeping close to upstream while applying aggressive tuning. The Project-C scheduler remains its main draw, though the broader Linux community has made strides with CFS improvements and sched-ext. That doesn't diminish the value of Liquorix for users who want a pre-tuned, low-latency experience out of the box.
This is a solid point release. The UAF fix is exactly the kind of maintenance that keeps the scheduler reliable when you're pushing your system hard.
