RUSTSEC-2026-0125
No affected components available
The AVX2 implementation of ML-DSA verification incorrectly implemented
the use_hint function, mishandling an edge case that should lead to
signature rejection.
Impact
An attacker could make the ML-DSA verifier accept a crafted invalid signature under a maliciously generated verification key, if the AVX2 implementation is used.
Mitigation
From version 0.0.9 the edge case is handled correctly and invalid
signatures are rejected.
