CVE-2026-22705
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. This issue has been patched in version 0.1.0-rc.2.
