Two Paths to Memory Safety: CHERI and OMA in the Fight Against Cyber Threats

Two architectural approaches have emerged to tackle the trillion-dollar memory safety problem at the hardware level: CHERI (Capability Hardware Enhanced RISC Instructions) and OMA (Object Memory Architecture). Both aim to make memory-unsafe code safe by design, but they take fundamentally different paths to get there. This article looks at the design differences and their impact on commercial applications.
