Improper Validation of Integrity Check Value

Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value in the processPacket method of KCCMBlockCipher, which invokes processAAD only when associated data is present, so with no AAD the G1 block nonce, length, flag is never mixed into the MAC and...

CVE-2026-54736

Phalcon is a high-performance, full-stack PHP framework. Prior to 5.14.1, Phalcon\Encryption\Crypt::decrypt compares the attacker-supplied HMAC tag against the freshly computed HMAC using PHP/Zephir identity comparison, which lowers to a byte-wise comparison that returns early on the first...

Linux Distros Unpatched Vulnerability : CVE-2026-6331

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility...

openssl: AES-OCB IV Ignored on EVP_Cipher() Path

A flaw was found in OpenSSL. Applications that use the AES-OCB encryption method with a specific one-shot interface EVPCipher will have their provided Initialization Vector IV silently discarded. This leads to the same internal cryptographic value being used repeatedly, which compromises the...

CVE-2026-45446 Incorrect Tag Processing for Empty Messages in AES-GCM-SIV and AES-SIV modes

Issue summary: The implementations of AES-SIV RFC 5297 and AES-GCM-SIV RFC 8452 mishandle the authentication of AAD Additional Authenticated Data with an empty ciphertext allowing a forgery of such messages. Impact summary: An attacker can forge empty messages with arbitrary AAD to the victim's...

CVE-2026-45445

CVE-2026-45445 describes a vulnerability in AES-OCB when using OpenSSL EVP_Cipher() in one-shot mode: the application-supplied IV is ignored, causing every encrypted message under the same key to use the same effective nonce. This leads to key/nonce reuse and potential confidentiality loss, and, ...

CVE-2026-5477

An integer overflow existed in the wolfCrypt CMAC implementation, that could be exploited to forge CMAC tags. The function wcCmacUpdate used the guard if cmac-totalSz != 0 to skip XOR-chaining on the first block where digest is all-zeros and the XOR is a no-op. However, totalSz is word32 and wrap...
