SCADAPack Secure Lock fixture verifier This repository is a deliberately bounded proof of concept for CVE-2026-81861. It verifies that two controlled fixtures produced with the vendor's shipped Windows DTM can be authenticated and decoded using common key material. It is not an operational exploi...
CVE-2026-56898
In aes256cmacsw of aes.rs, there is a possible way to forge message authentication codes over multi-block messages due to improperly used crypto. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...

Astra Linux – vulnerability in linux-6.1, linux-6.12
In the Linux kernel, the following vulnerability has been resolved: ksmbd: Compare MACs in constant time To prevent timing attacks, MAC comparisons must be performed in constant time. Replace memcmp with the appropriate function, cryptomemneq...
Astra Linux – vulnerability in linux-6.12
In the Linux kernel, the following vulnerability has been resolved: net/tcp-ao: Fix MAC comparison to be constant-time To prevent timing attacks, MACs need to be compared in constant time. Use the appropriate helper function for this...
A Zero-Knowledge Signature Framework for Efficient Post-Quantum Message Authentication in Cooperative Automated Driving
Connected and Automated Vehicles CAV rely on authenticated Vehicle-to-Everything V2X communications to exchange safety-critical information among vehicles and roadside infrastructure. As the automotive industry transitions toward post-quantum cryptography PQC, the significantly larger public keys...
CVE-2026-16001
Exposure of the message authentication key through the encryption keystream in the stream mode of IesEngine an IesEngine constructed without a block cipher in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows a remote attacker who has observed one encrypted message with known plainte...
CVE-2026-16001 IesEngine stream-mode MAC forgery via length-dependent KDF split
Exposure of the message authentication key through the encryption keystream in the stream mode of IesEngine an IesEngine constructed without a block cipher in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows a remote attacker who has observed one encrypted message with known plainte...

CVE-2026-16001
The Bouncy Castle Inc. bc-csharp library (versions before 2.7.0 ) is vulnerable to a message authentication key exposure in the IesEngine stream mode. Specifically, when an IesEngine is constructed without a block cipher, the MAC key is taken from the key derivation output immediately following a...
CVE-2026-12803
A flaw was found in Bouncy Castle for Java. The cryptographic module responsible for authenticated encryption does not correctly link a unique random value nonce with the message authentication code when no additional authenticated data is provided. This oversight could allow an attacker to forge...
CVE-2026-68119
The CVE-2026-68119 issue concerns the Linux kernel TCP-AO implementation: when constructing standalone TCP responses with TCP-AO options, the TCP header padding is not fully initialized if the MAC length is not four-byte aligned. The function tcp_ao_hash_hdr() writes only the MAC, leaving 1–3 pad...
Improper Validation of Integrity Check Value
Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value enabling MAC forgery, in the IESEngine class when initialized through the 4-argument init without a block cipher, where the KDF is seeded only from the ECDH shared secret and split into a...
Allocation of Resources Without Limits or Throttling
Overview org.bouncycastle:bcprov-jdk14 is a Java implementation of cryptographic algorithms. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the engineLoad method of BcFKSKeyStoreSpi, which reads HMAC PBKDF2 or scrypt cost parameters fro...
