RUSTSEC-2026-0076 Panic in Signature Hint Decoding During Verification

During ML-DSA verification the serialized hint values are decoded as specified in algorithm 22 HintBitUnpack of FIPS 204, subsection 7.1. The algorithm requires that the cumulative hint counters per row of the hint vector are strictly increasing and below a maximum value which depends on the choi...

ml-dsa's UseHint function has off by two error when r0 equals zero

Summary There's a bug in the usehint function where it adds 1 instead of subtracting 1 when the decomposed low bits r0 equal exactly zero. FIPS 204 Algorithm 40 is pretty clear that r0 0 means strictly positive, but the current code treats zero as positive. This causes valid signatures to...
