About this software

SUSE Linux Enterprise Live Patching applies kernel and selected executable updates to running SUSE systems without requiring a reboot. Delivered as signed RPMs and managed through standard update tools or SUSE Manager, it uses kGraft/klp live-patching technology to load kernel modules that replace functions at runtime. Live patches target high-severity security flaws and critical stability or data-corruption fixes and are tied to specific kernel revisions, complementing regular kernel updates that still require rebooting when necessary.

Frequently asked questions

What is SUSE Linux Enterprise Live Patching?
SUSE Linux Enterprise Live Patching applies kernel updates to a running system to address security and bug fixes without rebooting, helping maintain service continuity.
How does live patching reduce planned downtime?
By applying binary patches to the running kernel, it avoids reboot cycles for eligible fixes, allowing maintenance to occur without taking services offline.
Are there limitations to what can be patched live?
Only compatible kernel fixes that do not alter core data structures or interfaces can be applied; structural changes or major kernel upgrades require a reboot.
How should live patches be validated before production?
Validate patches in staging environments mirroring production, confirm compatibility with installed modules and applications, and follow existing change-management controls before deployment.
How is applicability of a live patch determined on a system?
Applicability is determined by compatibility checks against the running kernel; patches that fail those checks are withheld and must be applied with a reboot.
