kGraft is a feature of the Linux kernel that implements live patching of a running kernel, which allows kernel patches to be applied while the kernel is still running. By avoiding the need for rebooting the system with a new kernel that contains the desired patches, kGraft aims to maximize the system uptime and availability. At the same time, kGraft allows kernel-related security updates to be applied without deferring them to scheduled downtimes. Internally, kGraft allows entire functions in a running kernel to be replaced with their patched versions, doing that safely by selectively using original versions of functions to ensure per-process consistency while the live patching is performed.

  • kGraft es una característica del núcleo Linux que implementa la aplicación de parches en vivo de un kernel en ejecución, lo que permite que se apliquen parches del kernel mientras el kernel aún se está ejecutando. Al evitar la necesidad de reiniciar el sistema con un nuevo núcleo que contiene los parches deseados, kGraft apunta a maximizar el tiempo de actividad y disponibilidad del sistema. Al mismo tiempo, kGraft permite que las actualizaciones de seguridad relacionadas con el kernel se apliquen sin diferirlas a los tiempos de inactividad programados.​​ Internamente, kGraft permite que se reemplacen funciones completas en un kernel en ejecución con sus versiones parcheadas, haciendo esto de forma segura mediante el uso selectivo de las versiones originales de las funciones para asegurar (es)
