risc0 — Vulnerabilities & Security Advisories 4

RISC0 is an open-source zero-knowledge virtualization platform designed for secure computation, primarily used in blockchain and decentralized applications to verify execution integrity. Historically, it has been susceptible to remote code execution vulnerabilities due to memory corruption flaws in its zkVM implementation, along with privilege escalation issues from improper access controls. While no major public security incidents have been documented, the four recorded CVEs highlight persistent risks in input validation and memory safety. Its security model relies on formal verification, though real-world implementations have introduced exploitable edge cases, particularly in boundary conditions between guest and host environments.
