ML-DSA Signature Verification Accepts Signatures with Repeated Hint Indices
ghsa·2026-01-28
CVE-2026-24850 [MEDIUM] CWE-347 ML-DSA Signature Verification Accepts Signatures with Repeated Hint Indices
ML-DSA Signature Verification Accepts Signatures with Repeated Hint Indices
**Affected Crate:** `ml-dsa`
**Affected Versions:** v0.1.0-rc.2 (and commits since `b01c3b7`)
**Severity:** Medium
**Reporter:** Oren Yomtov (Fireblocks)
## Summary
The ML-DSA signature verification implementation in the RustCrypto `ml-dsa` crate incorrectly accepts signatures with repeated (duplicate) hint indices. According to the ML-DSA specification (FIPS 204 / RFC 9881), hint indices within each polynomial must be **strictly increasing**. The current implementation uses a non-strict monotonic check (` bool {
a.iter().enumerate().all(|(i, x)| i == 0 || a[i - 1] bool {
a.iter().enumerate().all(|(i, x)| i == 0 || a[i - 1] bool {
a.iter().enumerate().all(|(i, x)| i == 0 || a[i - 1] < *x)
}
```
## Design Intent
No detection rules found.
No public exploits indexed.
