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...
Detecting Hardware Trojans in Microprocessors via Hardware Error Correction Code-based Modules
Software-exploitable Hardware Trojans HTs enable attackers to execute unauthorized software or gain illicit access to privileged operations. This manuscript introduces a hardware-based methodology for detecting runtime HT activations using Error Correction Codes ECCs on a RISC-V microprocessor...

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...
