Summary

OpenVM prior to version 1.6.0 contains a vulnerability in the openvm-pairing guest library where the try_honest_pairing_check function does not check that the scaling factor s is in a proper subfield of Fp12. This allows incorrect results to the pairing check.

Risk Assessment

The risk is incorrect pairing check results, which could compromise the correctness of cryptographic proofs and potentially enable attacks on zkVM-based systems.

Recommendation

Update OpenVM to version 1.6.0 or later, which contains the fix.

Original NVD description (English source)

OpenVM is a performant and modular zkVM framework built for customization and extensibility. Prior to version 1.6.0, the openvm-pairing guest library's try_honest_pairing_check function invokes Theorem 3 of https://eprint.iacr.org/2024/640.pdf but does not check that the scaling factor s is in a proper subfield of Fp12. This allows incorrect results to the pairing check. This issue has been patched in version 1.6.0.
