What is CVE-2025-58157?

In version 0.12.0 of gnark, a zero-knowledge proof systems framework developed by Consensys, a denial of service vulnerability can be triggered during the scalar multiplication computation with the fake-GLV algorithm. This vulnerability occurs when the algorithm fails to converge within an acceptable timeframe for certain inputs, potentially leading to service disruption. The issue has since been resolved in version 0.13.0, which mitigates this vulnerability through optimized algorithm performance.
