arXiv:2609.01110v1 Announce Type: cross Abstract: CHERIoT is a novel hardware-software co-design that leverages hardware capabilities to define a notion of compartment, in a minimalistic capability-based OS, CHERIoT RTOS. By default, compartments are isolated to limit damage in case of bugs or malicious behaviour. To allow cross-compartment communication, the OS provides a privileged component, called the switcher. The switcher provides an interface for cross-compartment calls, while enforcing

Editorial Analysis

Why it matters

Formally verified hardware compartmentalisation could raise the security bar for OT/IoT devices that enterprises struggle to patch, reducing blast radius from compromised firmware.

What to do

Monitor CHERIoT ecosystem maturity for future procurement of embedded devices with formally verified isolation.
