CHERI Linux Working Group

Porting mainstream operating systems to CHERI hardware is key to mainstream adoption. The CHERI Linux working group focuses on defining and prioritising a roadmap for porting the Linux kernel and surrounding ecosystem to support CHERI’s capability-based security【96772754679130†L149-L156】. The group collaborates with upstream communities to integrate CHERI-specific changes and stimulate open‑source contributions【96772754679130†L149-L156】.

Activities include identifying kernel subsystems that require pointer safety annotations, adapting toolchains, porting userland libraries and testing on CHERI-enabled hardware. Contributors include kernel maintainers, security researchers and platform vendors.
