CVE-2025-9230 is an out-of-bounds read and write vulnerability in OpenSSL's RFC 3211 key-encryption-key unwrap functionality. An application decrypting Cryptographic Message Syntax (CMS) messages using password-based recipient information (PWRI) encryption can trigger invalid memory accesses. Malicious inputs can cause application crashes, memory corruption, or potentially execution of attacker-supplied code. Successful exploitation is considered unlikely, and CMS password-based encryption is rarely used. OpenSSL FIPS modules in the 3.5, 3.4, 3.3, 3.2, 3.1, and 3.0 branches are not affected because CMS processing is outside their module boundary.
