CVE-2026-22705 is a medium-severity vulnerability rated 6.4/10 on the CVSS scale. RustCrypto: Signatures offers support for digital signatures, which provide authentication of data using public-key cryptography. Prior to version 0.1.0-rc.2, a timing side-channel was discovered in the Decompose algorithm which is used during ML-DSA signing to generate hints for the signature. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
