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 AES-OCB IV Ignored on EVP_Cipher() Path

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-2026-9076 Out-of-Bounds Read in CMS Password-Based Decryption

Issue summary: When CMS password-based decryption RFC 3211 / PWRI key unwrap processes attacker-supplied CMS data, an attacker-chosen stream-mode KEK cipher can trigger a heap out-of-bounds read in kekunwrapkey. Impact summary: A heap buffer over-read may trigger a crash which leads to Denial of...

RUSTSEC-2026-0209 AES-GCM did not enforce limits on AAD length

NIST Special Publication 800-38D specifies that the bit length of the AAD shall not exceed 2^64 - 1 bits. The implementation of AES-GCM in libcrux-aesgcm neither enforced this limit for encryption nor for decryption. Impact Use of AES-GCM with AAD of length exceeding the prescribed maximum length...

x86: mismatched mapcache metadata

ISSUE DESCRIPTION Some shadow paging errors paths will switch the page-tables without updating the currently running vCPU reference. This causes a mismatch between the loaded page-tables and the mapcache metadata which can lead to corruption of the mapcache. IMPACT Privilege escalation, Denial of...
