In an era where security threats continually evolve, protecting the heart of an operating system, the kernel, has never been more critical. One tool gaining traction in the Linux world is the Linux Kernel Runtime Guard (LKRG), a specialized security module designed to detect and respond to attacks targeting the kernel while the system is running. This project recently reached its first stable milestone with version 1.0.0, marking a major step forward for runtime protection on Linux systems.
What Is LKRG?LKRG (short for Linux Kernel Runtime Guard) is a loadable kernel module that continuously monitors the health and integrity of the Linux kernel while it’s running. Unlike many security features that rely on compile-time patches or static defenses, LKRG acts at runtime, watching for signs of unauthorized changes or exploit attempts and taking configurable action when something suspicious is detected.
Because LKRG is a module rather than a patch to the kernel source, it can be built and used across a variety of distributions and kernel versions without needing to recompile the core kernel itself. It supports a wide range of architectures, including x86-64, 32-bit x86, ARM64, and 32-bit ARM, and has been tested on kernels from older enterprise releases all the way up to recent mainline versions.
How LKRG WorksAt its core, LKRG performs runtime integrity checks on critical parts of the kernel and system state. It validates the kernel’s code, data, and metadata against expected values and monitors for unexpected changes that could be indicative of an exploit. The module also watches key process attributes and credentials to help spot unauthorized privilege escalation attempts.
Unlike compile-time defenses such as address space layout randomization (ASLR) or static code hardening, LKRG is designed to observe and react while the kernel is executing, a concept sometimes referred to as “post-detection” security. This complements other layers of defense rather than replacing them.
Version 1.0: A Milestone ReleaseAfter several years of development, with the first public release appearing back in 2018, LKRG has finally reached its 1.0 release, signaling maturity and broader real-world readiness. This milestone brings a suite of improvements, including:

Mozilla has taken a notable step toward improving Firefox distribution on Linux. An official Firefox RPM package is now available directly from Mozilla for Fedora-style distributions, including Fedora, RHEL-compatible systems, and related derivatives. This move gives users a new, upstream-supported option for installing and maintaining Firefox without relying solely on distro-maintained builds.
What’s ChangedUntil now, users on RPM-based systems typically installed Firefox through their distribution’s repositories. While those packages are usually well-maintained, they can sometimes lag behind Mozilla’s release schedule or include distro-specific patches.
With the new official RPM, Mozilla provides:
A Firefox build maintained directly by Mozilla
Faster access to new releases and security updates
A consistent Firefox experience across RPM-based distros
Reduced dependency on downstream packaging delays
This mirrors the approach Mozilla already uses for official DEB packages and tarball releases, bringing parity to RPM-based ecosystems.
Who Benefits MostThis new packaging option is especially useful for:
Fedora users who want Firefox updates the moment Mozilla releases them
Developers and testers who need predictable, upstream Firefox behavior
Enterprise or workstation users running Fedora-derived systems who prefer vendor-supplied binaries
Users who want to avoid Flatpak or Snap for their browser
Distributions that prioritize stability over immediacy may still ship older versions, but the official RPM gives users a clear choice.
How It WorksMozilla hosts a signed RPM repository that integrates cleanly with dnf-based systems. Once added, Firefox updates arrive through the standard system update process, just like any other RPM package.
Key characteristics include:
GPG-signed packages from Mozilla
Automatic updates via dnf upgrade
No repackaging or third-party rebuilds
Compatibility with Fedora and compatible RPM distros
Users can choose between the distro-provided Firefox or Mozilla’s upstream RPM without conflict, as long as only one source is enabled.
Why This Matters for Linux UsersThis change reflects a broader trend: upstream projects taking more responsibility for how their software reaches users. For Firefox, that means:
