Security Concerns Plague Emerging Chip Architecture

The report warns that RISC-V's open-source adoption exposes the hardware supply chain to serious security risks — notably the GhostWrite flaw in the Xuantie C910 vector extension that permits privileged-memory access — and emphasizes that faulty or malicious silicon designs are hard to patch in the field, posing significant risks to automotive, industrial, and critical infrastructure; it recommends relying on established vendors and security standards (e.g., Caliptra) to mitigate these risks.
