SUSE 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...
openssl: Incorrect Tag Processing for Empty Messages in AES-GCM-SIV and AES-SIV modes
A flaw was found in OpenSSL. The implementations of AES-SIV Advanced Encryption Standard - SIV and AES-GCM-SIV Advanced Encryption Standard - Galois/Counter Mode - SIV incorrectly process authentication tags for empty messages. This vulnerability allows a remote attacker to forge empty messages...

CVE-2026-45446
The OpenSSL provider implementation for AES-SIV (RFC 5297) and AES-GCM-SIV (RFC 8452) mishandles Additional Authenticated Data (AAD) authentication when the ciphertext is empty. Because the expected tag is only computed during decryption with non-empty data, calling EVP_DecryptFinal_ex() on an em...
