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...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...

CVE-2025-30156

A flaw was found in the CephX authentication protocol used by Ceph, a distributed storage system. CephX uses AES-128-CBC encryption with a hardcoded initialization vector and no message authentication HMAC, making it vulnerable to the same class of unauthenticated-encryption attacks that...

Generation of Predictable IV with CBC Mode

Affected versions of this package are vulnerable to Generation of Predictable IV with CBC Mode via AesBytesEncryptor when using the two-argument constructor or specifying a null I...

libkcapi: IV reuse in libkcapi one-shot symmetric cipher chunking causes cipher state reset across chunk boundaries

A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs over 64 KiB in stateful modes such as Counter CTR or Cipher Block Chaining CBC, the library improperly reuses the Initialization Vector IV for each internal data chunk. A remote attacker could...
