LTS kernel support period Linux 5.4 and 4.19, maintained by Greg Kroah-Hartman () and Sasha Levin (Sasha Levin), until December 2025 and 2024, respectively. Core Linux 4.19 is used in Debian 10 Google as the basis for the basic universal core Android and comes in a platform Android 10, and kernel 5.4 is used in Ubuntu 20.04 LTS.
Thus, as with kernels 3.16, 4.9, 4.4, and 4.14, the 5.4 and 4.19 branches will be supported for 6 years. These kernels were originally planned to be supported for 2 years (until December 2020 and 2021). Kernel support Linux 3.16, released in August 2014, reaches the end of its support in June 2020. The 4.14 kernel will be supported until January 2024, 4.9 until January 2023, and 4.4 until February 2022. For regular non-LTS kernel releases, updates are released only until the next stable branch is released (for example, updates for the 5.6 branch were released until 5.7).
Separately based on kernels 4.4 and 4.19 by the organization Linux Foundation branch (Super Long Term Support), which are maintained separately and will be supported for 10-20 years. Maintenance of SLTS branches is carried out within the framework of the Civil Infrastructure Platform (CIP) project, which involves companies such as Toshiba, Siemens, Renesas, Hitachi, and MOXA, as well as the maintainers of the LTS branches of the main kernel, developers Debian and the creators of the KernelCI project. SLTS kernels are targeted for use in civil infrastructure systems and critical industrial systems.
