📰 Ubuntu brings Livepatch to arm64 for rebootless kernel updates

Canonical has brought Livepatch to Arm64 devices for the first time, allowing Ubuntu systems on Arm hardware to apply critical kernel security patches without a full reboot. Livepatch is one of Ubuntu’s best hidden security features – it’s not enabled by default, requires Ubuntu Pro – as it allows kernel security updates to be applied in memory while your system is running. Normally, a restart is needed.
