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...
pqc_kyber: AVX2 backend skips Fujisaki-Okamoto implicit rejection, enabling chosen-ciphertext key recovery
Summary When pqckyber is built with the opt-in avx2 feature on x8664, its constant-time conditional-move routine cmov is a no-op: it never performs the copy. That cmov is exactly the step that applies the Fujisaki-Okamoto FO implicit rejection during decapsulation. With it disabled, decapsulating...

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...
