Linux Kernel Support Extended: What You Need to Know

Introduction to Linux Kernel Updates

Greg Kroah-Hartman has recently updated the projected end-of-life (EOL) dates for several active longterm support kernels. This change was made based on discussions with various companies, groups, and the other stable kernel maintainer, Sasha Levin.

Meanwhile, the updated support schedule for currently active LTS kernels is now available. For example, Linux 6.6 now has an EOL date of December 2027, giving it a 4-year support window. Additionally, Linux 6.12 and 6.18 also have extended support windows.

Understanding Linux Kernel Support

However, it’s worth noting that most Linux kernel releases only get about two months of active support. Nevertheless, LTS releases are an exception, receiving years of backported security patches and bug fixes without new features.

Furthermore, back in 2023, it was announced that LTS support windows would be cut from six years to two due to contributor burnout. Nevertheless, the recent change pushes back against this shorter support window, at least for the current batch of LTS kernels.

Impact on Linux Users

For most desktop Linux users, this change is barely noticeable. Meanwhile, users of Ubuntu, Fedora, or other mainstream distros don’t need to keep track of specific kernel releases, as their distro handles updates for them.

However, for those running embedded systems, single-board computers, or servers, EOL dates are crucial. Once a kernel hits EOL, it stops receiving security patches, making the longer support window relevant for hardware vendors and device manufacturers.

What This Means for You

In conclusion, if you’re a regular Linux user, nothing changes today. Nevertheless, if you depend on a specific LTS kernel for critical applications, you now have more breathing room than before.

Additionally, the extended support window is also relevant for companies that certify their products against specific kernel versions. Knowing that a kernel will be patched until 2028 instead of 2026 changes the math on when an upgrade cycle needs to start.

FAQs

Here are some frequently asked questions about Linux kernel support:

  • What is the focus keyword for this article? The focus keyword is Linux kernel support.
  • How often do Linux kernel releases get updated? Most releases get about two months of active support before the next one takes over.
  • What is the difference between LTS and non-LTS kernel releases? LTS releases receive years of backported security patches and bug fixes without new features.
  • How does the extended support window affect hardware vendors and device manufacturers? The longer support window gives them more time to certify their products against specific kernel versions.
  • What should I do if my Linux distro is still running an outdated kernel? You should consider upgrading to a newer version or switching to a distro that handles kernel updates for you.
