CVE-2024-50354Public exploit

Prover or verifier crash via unbounded key allocation

Published Oct 31, 2024 · Updated Oct 31, 2024

Uncontrolled resource consumption in Consensys gnark 0.11.0 and earlier allows local users to crash a prover or verifier. ReadFrom trusts the serialized Groth16 header's nbCommitments value and uses it as a slice length before validating the available commitment keys. Local users with low privileges need only supply a malicious proving or verification key, causing out-of-memory termination without data disclosure or modification.
