CVE-2026-74900

openssl_encrypt before version 1.4.0 has a flaw in pqc.py: when KEM decapsulation fails, it silently falls back to simulation mode, deriving a deterministic shared secret from just 16 bytes of the private key plus public encapsulated key data. An attacker with those 16 private-key bytes can compu...

CVE-2024-14041

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...

Linux Distros Unpatched Vulnerability : CVE-2026-6330

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The ML-KEM ARM64 NEON ciphertext comparison only compares half of the input, breaking the Fujisaki-Okamoto transform's implicit rejection and weakening IND-CCA2...

CVE-2026-6330

The ML-KEM ARM64 NEON ciphertext comparison only compares half of the input, breaking the Fujisaki-Okamoto transform's implicit rejection and weakening IND-CCA2 security on that code path. The constant-time comparison effectively ignored part of the re-encrypted ciphertext, so a decapsulating par...

CVE-2026-6330

CVE-2026-6330 : In ML-KEM targeting ARM64 NEON, the ciphertext comparison only checks half of the input. This breaks the Fujisaki-Okamoto transform’s implicit rejection, weakening IND-CCA2 security on that path. The constant-time comparison thus ignores part of the re-encrypted ciphertext, allowi...

CVE-2026-10097 ML-KEM-1024 x64 AVX2 incomplete cipher text comparison enables IND-CCA2 break and static private-key recovery

wolfSSL's AVX2-optimized ML-KEM implementation mlkemcmpavx2 compares only 1536 of the 1568 ciphertext bytes during the Fujisaki-Okamoto re-encryption check in ML-KEM-1024 decapsulation. Ciphertexts that differ from the expected re-encryption solely in bytes 1536-1567 bypass implicit rejection and...

CVE-2026-10097

Summary: CVE-2026-10097 affects wolfSSL’s ML-KEM-1024 x64 AVX2 implementation. The Fujisaki-Okamoto decapsulation path performs an incomplete ciphertext check, failing to compare the final portion of the 1568-byte ciphertext. As a result, ciphertexts manipulated in those final bytes can bypass im...
