KernelCare patches vulnerabilities on Arm-based devices while they are running and without a reboot.

Learn more

KernelCare live patching keeps the Linux systems you run on Arm-based machines protected against the latest vulnerabilities. This is done without downtime, reboots, or service interruption.

KernelCare in action

KernelCare binary-patches the Linux kernel as a binary in memory. There is no need to update system libraries or packages to keep in step with kernel changes. This is not the case when using traditional Linux update tools such as yum and apt-get.

Supported processors

KernelCare supports 64-bit Arm Cortex, Neoverse, SecurCore, and the next generation of AWS EC2 Graviton2 instances. KernelCare also supports Arm-based processors commonly used in IoT, such as NXP, allowing users to apply security patches to the running Arm-based machines automatically, and without downtime.
