Linux Kernel Support Extended: LTS Releases Now Backed Until 2028

In a move that’s sending ripples through the Linux community, Greg Kroah-Hartman, the lead maintainer of the Linux kernel, has just announced extended end-of-life (EOL) dates for several active long-term support (LTS) kernel releases. This update, delivered via a commit to the kernel documentation, represents a significant shift in the support landscape for one of the world’s most critical open-source projects.

The New Support Timeline: What’s Changed?

The updated support schedule for currently active LTS kernels now looks like this:

• Linux 6.6 now EOLs December 2027 (previously December 2026), securing a 4-year support window.
• Linux 6.12 now EOLs December 2028 (previously December 2026), also guaranteeing a 4-year support window.
• Linux 6.18 now EOLs December 2028 (previously December 2027), providing at least 3 years of support.

This extension comes after “lots of discussions with different companies and groups and the other stable kernel maintainer,” according to Kroah-Hartman’s commit message. The other maintainer in question is Sasha Levin, who co-maintains these Linux kernel releases alongside Greg.

Why This Matters: The Kernel Support Ecosystem

For those not deeply embedded in kernel development, it’s worth understanding the significance of this change. Most Linux kernel releases only receive about two months of active support before the next version takes over. LTS releases, however, are the exception to this rapid release cycle.

LTS kernels receive years of backported security patches and bug fixes without introducing new features, making them ideal for desktop environments, embedded hardware, and servers that prioritize stability over cutting-edge functionality.

A Look Back: The 2023 Support Window Controversy

This extension represents a partial reversal of a controversial decision made in 2023. At the Open Source Summit Europe event, it was revealed that LTS support windows were being dramatically reduced from six years down to just two. The primary reason cited was maintainer burnout—too many contributors were working unpaid and struggling to handle the flood of bugs generated by fuzzing tools.

While this recent change doesn’t fully restore the previous six-year support window, it does push back against the shorter support timeline, at least for the current batch of LTS kernels.

Who Needs to Pay Attention?

For most desktop Linux users running mainstream distributions like Ubuntu, Fedora, or others, this change is largely invisible. Your distribution handles kernel updates automatically, and you’ll be notified when updates are available. The kernel side of things is essentially managed for you.

However, this extension is critically important for:

Embedded Systems and IoT Devices: Manufacturers of embedded systems, single-board computers, and IoT devices often certify their products against specific kernel versions. Knowing that a kernel will be patched until 2028 instead of 2026 fundamentally changes their upgrade planning calculus.

Enterprise Servers: Organizations running LTS kernels on production servers benefit from the extended security patch window, reducing the frequency of disruptive kernel upgrades.

Hardware Vendors: Companies that ship Linux on their products need to consider kernel support timelines when planning product lifecycles and support commitments.

Specialized Use Cases: Anyone running critical infrastructure on specific LTS kernel versions now has more breathing room before needing to plan migration strategies.

The Security Implications

Once a kernel hits its EOL date, it stops receiving security patches. This creates a vulnerable window where known security issues remain unpatched. The extended support timeline means organizations and individuals can maintain secure systems for longer periods without the disruption of kernel upgrades.

Looking Ahead

The Linux kernel continues to be one of the most complex and critical pieces of software in the world, powering everything from smartphones to supercomputers. This extension of support timelines reflects the growing maturity of the Linux ecosystem and the increasing importance of long-term stability for enterprise and embedded deployments.

For regular users, nothing changes today—your system will continue updating as normal. But for anyone depending on a specific LTS kernel for critical operations, you’ve just gained valuable additional time before needing to plan your next move.
