CVE-2024-14041 ML-KEM (Kyber) decapsulation leaks private key information through non-constant-time division in message decoding and ciphertext compression (KyberSlash)

In Bouncy Castle for Java from 1.73 to before 1.78, three ML-KEM CRYSTALS-Kyber routines divided secret-derived polynomial coefficients by the modulus q: Poly.toMsg, which decodes the decrypted message, and the ciphertext compression routines Poly.compressPoly and PolyVec.compressPolyVec. An...
