What is CVE-2023-44273?

The gnark-crypto library developed by Consensys is vulnerable to signature malleability due to improper deserialization of EdDSA and ECDSA signatures. This vulnerability allows an attacker to manipulate the digital signature without invalidating it, posing risks to the integrity of cryptographic operations. Specifically, the deserialization process does not adequately ensure that the signature data falls within a specific range, which can lead to unintended consequences in secure communications and data integrity.
