*Upgrade and reboot interval: Security patches are created for a kernel for up to 9–13 months from its release date. Upgrade and restart the machine within this period to continue receiving Livepatch patches. New kernel ABIs are provided during the Ubuntu Pro security coverage period.
GA refers to the kernel a release launched with. HWE (Hardware Enablement) kernels are newer kernels introduced into the current LTS release as they ship with subsequent Ubuntu versions, up until the next LTS release.
Livepatch provides HWE kernel support for a limited combination of kernel flavour, kernel version, and Ubuntu release, as described in the table above.
Livepatch provides security coverage for ARM64 (arm64) architectures from release 26.04 onward. Older releases are not covered for the ARM64 architecture due to limitations in the available tooling.
For help diagnosing why a specific kernel may not be receiving patches, see the troubleshooting guide.
