Astra Linux – Vulnerability in nss

The NSS code used for checking PKCS1 v1.5 was leaking information useful for launching Bleichenbacher-style attacks. Both the overall correctness of the padding and the length of the encrypted message were exposed through timing side-channels. By sending a large number of ciphertexts selected by...

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

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...

EUVD-2026-39553

ML-KEM-1024 x64 AVX2 implicit rejection failure in the Fujisaki-Okamoto transform breaks IND-CCA2 security, allowing decapsulation to deviate from the implicit-rejection behavior required by the standard. The AVX2 constant-time ciphertext comparison used during decapsulation never compared the...
