CVE-2026-45446

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

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...

PT-2026-61580

Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 3.28.0 Description A heap-based buffer overflow exists in the crypto rsa common function within the libfreerdp/crypto/crypto.c file. The issue occurs because the function uses BN bn2bin to write a modular-exponentiati...

PT-2026-47843

Name of the Vulnerable Software and Affected Versions OpenSSL versions 3.0 through 3.3 Description The implementations of AES-SIV and AES-GCM-SIV mishandle the authentication of Additional Authenticated Data AAD when the ciphertext is empty, which allows for the forgery of such messages. In the...
