CVE-2026-47842

Spring Security 's AesBytesEncryptor deterministically encrypts data with AES/CBC when the two-argument constructor is used or a null IV generator is passed with CBC mode, resulting in a null (all-zero) initialization vector . This causes identical plaintexts to always produce identical ciphertex...

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...

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...

openssl: heap buffer overflow in CMS key unwrapping

A flaw was found in OpenSSL. A crafted CMS Cryptographic Message Syntax message can cause an 8-byte out-of-bounds heap write when it is decrypted with CMSdecrypt. This issue occurs because the CMS decryption process incorrectly sizes the key-unwrap output buffer when using the AES-WRAP-PAD unwrap...

openssl: heap buffer overflow in CMS key unwrapping

A flaw was found in OpenSSL. A crafted CMS Cryptographic Message Syntax message can cause an 8-byte out-of-bounds heap write when it is decrypted with CMSdecrypt. This issue occurs because the CMS decryption process incorrectly sizes the key-unwrap output buffer when using the AES-WRAP-PAD unwrap...

CVE-2026-63072

A flaw was found in OpenSSL. A crafted CMS Cryptographic Message Syntax message can cause an 8-byte out-of-bounds heap write when it is decrypted with CMSdecrypt. This issue occurs because the CMS decryption process incorrectly sizes the key-unwrap output buffer when using the AES-WRAP-PAD unwrap...

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...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write due to buffer sizing in cmskekcipher in crypto/cms/cmskari.c and crypto/cms/cmskemri.c. An attacker can corrupt the heap and trigger a denial of service by supplying a crafted CMS message that is decrypted with...

Improper Validation of Integrity Check Value

Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value in the chacha20poly1305cipher and aesocbcipher implementations under providers/implementations/ciphers/. An attacker can forge messages by supplying an empty ciphertext and a bad tag, then...
