Summary

libcrux incorrectly calculates on aarch64

Details

On platforms without the core::arch::aarch64::vxarq_u64 intrinsic, an unverified fallback in libcrux-intrinsics v0.0.3 passed incorrect arguments and produced wrong results. This corrupted SHA-3 digests and caused libcrux-ml-kem and libcrux-ml-dsa to sample incorrectly, yielding incorrect shared secrets and invalid signatures.

The issue has been fixed in v0.0.4.
