Linux 5.10 and 5.15: projected EOL December 2026

The kernel.org longterm table shows 5.15 and 5.10 with a projected end of life of Dec, 2026. It's a projection, and the page calls these longterm maintenance kernels.

Longterm	Released	Projected EOL
6.18	2025-11-30	Dec, 2028
6.12	2024-11-17	Dec, 2028
6.6	2023-10-29	Dec, 2027
6.1	2022-12-11	Dec, 2027
5.15	2021-10-31	Dec, 2026
5.10	2020-12-13	Dec, 2026

Example

Illustrative. uname -r prints 5.15.0-100-generic. Anything after the dash means a distribution kernel, so the date to follow is your distribution's. A plain 5.15.170 on an appliance you built yourself is the case this table is about.

Important

kernel.org says its developers can provide no support for distribution kernels. Those go to your vendor's support channels.

Sort your fleet

• ☐ Run uname -r per host group
• ☐ Separate distribution kernels from your own builds
• ☐ Check embedded boards and appliances
• ☐ Date each move off 5.10 and 5.15
