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 experiences an implicit rejection failure in the Fujisaki-Okamoto transform, breaking IND-CCA2 security. The AVX2 constant-time ciphertext comparison during decapsulation does not compare the final 32-byte block of the 1568-byte ciphertext, so a ciphertext manipulated in thos...

CVE-2026-10097

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...

OESA-2026-2612 nss security update

Network Security Services NSS is a set of libraries designed to support cross-platform development of security-enabled client and server applications. Applications built with NSS can support SSL v2 and v3, TLS, PKCS 5, PKCS 7, PKCS 11, PKCS 12, S/MIME, X.509 v3 certificates, and other security...

PT-2026-47838

Name of the Vulnerable Software and Affected Versions OpenSSL affected versions not specified Description The CMS decrypt and PKCS7 decrypt functions are susceptible to a Bleichenbacher-style attack, which is an adaptive-chosen-ciphertext side channel. This allows an attacker to use a vulnerable...

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...

The vulnerability of the openssl_private_decrypt() function in the PKCS1 Padding Handler component of the PHP programming language interpreter allows a attacker to execute a Marvin attack.

The vulnerability of the opensslprivatedecrypt function in the PKCS1 Padding Handler component of the PHP programming language interpreter is related to the use of an OpenSSL version that does not include the changes required by the RSAPKCS1IMPLICITREJECTION request. Exploiting this vulnerability...

CVE-2024-2467

A timing-based side-channel flaw exists in the perl-Crypt-OpenSSL-RSA package, which could be sufficient to recover plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an attacker would have to be able to send a large number of trial messages. The...
