Vulnerability Discovered: Dirty Frag

A new security vulnerability called Dirty Frag has been discovered in the Linux kernel. This vulnerability could potentially allow local attackers to escalate privileges on affected systems.

Upgrade Available Now

I have updated the CachyOS kernel builds in COPR to versions 7.0.5 and 6.18.28, which contain the necessary security patches.

Packages: kernel-cachyos (standard), kernel-cachyos-lts (LTS), kernel-cachyos-server, kernel-cachyos-rt, plus LTO variants
Platforms: Fedora and Enterprise Linux (RHEL, AlmaLinux, Rocky Linux, etc.)
Repository: COPR kernel-cachyos

What is the CachyOS Kernel?

The CachyOS kernel is an optimized Linux kernel focused on performance and latency. It includes:

Btrfs and ZFS optimizations
CPU scheduler tweaks for better responsiveness
Memory management improvements
Latest security patches

Perfect for both workstations and servers where performance matters.

Upgrade Immediately

I urge all users to upgrade as soon as possible. Security vulnerabilities should never be ignored — especially when a fix is already available.

To upgrade:

sudo dnf update kernel-cachyos*

Remember to reboot after the upgrade to ensure you're running on the new kernel.

Verify Your Kernel Version

After rebooting, confirm you're running the secure version:

uname -r

You should see 7.0.5 or 6.18.28 in the output.
