CVE-2026-24850 is a regression bug in the RustCrypto ml-dsa crate (versions 0.0.4 to 0.1.0-rc.3), a Rust implementation of the ML-DSA digital signature standard. The vulnerability allows the signature verification process to incorrectly accept signatures containing duplicate hint indices, which violates the "strictly increasing" requirement of the ML-DSA specification. This medium-severity vulnerability (CVSS 5.3) has a low impact, primarily affecting integrity by allowing invalid signatures to be accepted. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
