CVE-2026-53762

VeraCrypt provides disk encryption with strong security based on TrueCrypt. Prior to 1.26.29, non-default builds created with WOLFCRYPT=1 and WOLFCRYPTBACKEND route SHA-256 and SHA-512 volume-header key derivation through derivekeysha256 and derivekeysha512 in src/Crypto/wolfCrypt.c, where the...

CVE-2026-53762

VeraCrypt non-default builds compiled with WOLFCRYPT=1 and WOLFCRYPT_BACKEND contain a key-derivation flaw in src/Crypto/wolfCrypt.c. The functions derive_key_sha256 and derive_key_sha512 discard the configured iteration count and substitute wc_HKDF for PBKDF2-HMAC , meaning increasing the PIM or...

CVE-2026-53762 VeraCryp: wolfCrypt backend bypasses VeraCrypt PBKDF2 iteration count (non-default WOLFCRYPT=1 builds)

VeraCrypt provides disk encryption with strong security based on TrueCrypt. Prior to 1.26.29, non-default builds created with WOLFCRYPT=1 and WOLFCRYPTBACKEND route SHA-256 and SHA-512 volume-header key derivation through derivekeysha256 and derivekeysha512 in src/Crypto/wolfCrypt.c, where the...

CVE-2026-74889

opensslencrypt versions before 1.4.0 use HKDF with no salt and static info parameter in key normalization functions, reducing entropy extraction and determinism. Attackers can exploit predictable key derivation with identical inputs to weaken cryptographic security against multi-target attacks...

CVE-2026-74889 openssl_encrypt before 1.4.0 Weak Key Derivation via HKDF

opensslencrypt versions before 1.4.0 use HKDF with no salt and static info parameter in key normalization functions, reducing entropy extraction and determinism. Attackers can exploit predictable key derivation with identical inputs to weaken cryptographic security against multi-target attacks...

CVE-2026-74889 openssl_encrypt before 1.4.0 Weak Key Derivation via HKDF

CVE-2026-74889

The openssl_encrypt library (PHP package) before version 1.4.0 uses HKDF with no salt and a static info parameter in its key normalization functions, producing deterministic, low-entropy derived keys. Attackers with identical inputs can predict derived keys, weakening cryptographic security again...

CVE-2026-41207

The netty incubator codec.bhttp is a java language binary http parser. Prior to version 0.0.21.Final, HKDFexpand returns non-NULL on failure. The byte is filled with zeros and has no way to distinguish success from failure. Since this output is used as HKDF key material for the response AEAD, a...

CVE-2026-41207 netty-incubator-codec-ohttp's HPKEContext operations may produce empty byte[] on failures

The netty incubator codec.bhttp is a java language binary http parser. Prior to version 0.0.21.Final, HKDFexpand returns non-NULL on failure. The byte is filled with zeros and has no way to distinguish success from failure. Since this output is used as HKDF key material for the response AEAD, a...

netty-incubator-codec-ohttp 安全特征问题漏洞

netty-incubator-codec-ohttp is an application developed by the Netty community. Versions prior to 0.0.21.Final of netty-incubator-codec-ohttp contain a security vulnerability. This vulnerability arises from returning a non-empty value when HKDF-expand fails, which may lead to the use of a key wit...

Insecure Randomness

Overview Affected versions of this package are vulnerable to Insecure Randomness due to the HKDFexpand and EVPHPKECTXexport functions returning a zero-filled byte array on failure, which is then used as key material for AEAD encryption. An attacker can predict and exploit the deterministic,...

netty-incubator-codec-ohttp's HPKEContext operations may produce empty byte[] on failures

HKDFexpand: returns non-NULL on failure. The byte is filled with zeros and has no way to distinguish success from failure. Since this output is used as HKDF key material for the response AEAD, a failure silently produces an all-zero key. When EVPHPKECTXexport fails it also returns an empty byte...

CVE-2026-41676

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.27 to before 0.10.78, Deriver::derive and PkeyCtxRef::derive sets len = buf.len and passes it as the in/out length to EVPPKEYderive, relying on OpenSSL to honor it. On OpenSSL 1.1.x, X25519, X448, DH and HKDF-extra...
