Name of the Vulnerable Software and Affected Versions: RISC Zero versions prior to 2.1.1 and 2.2.0 Description: The issue concerns the Steel.validateCommitment Solidity library function, which returns true for a crafted commitment with a digest value of zero. This violates the function's semantic...

RISC Zero Ethereum 安全漏洞

RISC Zero Ethereum is a computing platform open-sourced by RISC Zero. A security vulnerability exists in RISC Zero Ethereum versions prior to 2.1.1 and 2.2.0, which stems from the Steel.validateCommitment function returning true for a commitment with a summary value of zero, which could lead to a...

CVE-2025-52484

RISC Zero is a general computing platform based on zk-STARKs and the RISC-V microarchitecture. Due to a missing constraint in the rv32im circuit, any 3-register RISC-V instruction including remu and divu in risc0-zkvm 2.0.0, 2.0.1, and 2.0.2 are vulnerable to an attack by a malicious prover. The...

CVE-2025-52484

The CVE concerns risc0-zkvm prior to version 2.1.0. A missing constraint in the rv32im circuit allows a malicious prover to exploit any 3-register RISC-V instruction (e.g., remu, divu) by making rs1 appear equal to rs2, potentially compromising zkVM computations. Affected releases: risc0-zkvm 2.0...
