kpatch is a Linux dynamic kernel patching infrastructure that lets sysadmins apply critical security patches to a running kernel without rebooting or restarting processes. It is now deprecated and in maintenance mode, with its kpatch-build functionality replaced by the upstream klp-build tool in Linux 6.19+.
Use cases
- patch a running linux kernel without rebooting
- apply critical kernel security fixes immediately without downtime
- avoid reboots while keeping the kernel patched
- live patch the kernel on production servers
- build kernel live patches from source diffs
When to choose
- you need to apply kernel security patches to running systems without rebooting
- you run older kernels (pre-6.19) on x86-64, ppc64le, arm64, s390, or loongarch64 and need live patching
- you want more control over uptime without sacrificing security
When to avoid
- you are on Linux 6.19 or newer - use the upstream klp-build tool instead
- you need new features or support for the latest kernels and toolchains
- you cannot tolerate the risk of kernel crashes or data loss from live patching
