CVE-2026-81020 wolfEngine reuses the AES-GCM nonce on every TLS 1.2 / DTLS 1.2 record
wolfEngine before 1.4.1 generates the 8-byte explicit AES-GCM nonce once when the TLS write key is set and never increments it per record. As a result every TLS 1.2 and DTLS 1.2 AES-GCM record within a connection is encrypted under an identical key and nonce pair. Reusing a GCM key and nonce...

CVE-2026-81020
wolfEngine before 1.4.1 generates the 8-byte explicit AES-GCM nonce only once when the TLS write key is set and never increments it per record. Consequently, every TLS 1.2 and DTLS 1.2 AES-GCM record within a connection is encrypted under an identical key and nonce pair. GCM nonce reuse discloses...
CVE-2026-81019 wolfProvider reuses the AES-GCM nonce on every TLS 1.2 / DTLS 1.2 record
wolfProvider before 1.2.2 generates the 8-byte explicit AES-GCM nonce once when the TLS write key is set and never increments it per record. As a result every TLS 1.2 and DTLS 1.2 AES-GCM record within a connection is encrypted under an identical key and nonce pair. Reusing a GCM key and nonce...

CVE-2026-81019
wolfProvider (by wolfSSL) versions before 1.2.2 generate the 8-byte explicit AES-GCM nonce once when the TLS write key is set and never increment it per record. Consequently, every TLS 1.2 and DTLS 1.2 AES-GCM record in a given connection is encrypted with an identical key and nonce pair. Reusing...
Improper Validation of Integrity Check Value
Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value in CMS AuthEnvelopedData recipient processing, where AbstractRecipient and its recipient classes such as JceKeyTransRecipient and BcKeyTransRecipient take the AEAD tag length from the...

Improper Validation of Integrity Check Value
Overview org.bouncycastle:bcprov-jdk12 is a Java implementation of cryptographic algorithms. 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...
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...

AZL-89937 CVE-2026-45446 affecting package openssl for versions less than 3.3.7-3
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...
AZL-90087 CVE-2026-45445 affecting package openssl for versions less than 3.3.7-3
Issue summary: When an application drives an AES-OCB context through the public EVPCipher one-shot interface, the application-supplied initialisation vector IV is silently discarded. Impact summary: Every message encrypted under the same key uses the same effective nonce regardless of the IV...
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...
