CheriBSD is a Capability Enabled, Unix-like Operating System which takes advantage of Capability Hardware on Arm's Morello and CHERI-RISC-V platforms, and is developed by SRI International and the University of Cambridge.

CheriBSD extends FreeBSD to implement memory protection and software compartmentalization features supported by the CHERI ISA. CheriBSD includes support for CHERI extensions to the RISC-V and Arm/Morello architectures.
