CVE-2025-15467

A flaw was found in OpenSSL. A remote attacker can exploit a stack buffer overflow vulnerability by supplying a crafted Cryptographic Message Syntax (CMS) message with an oversized Initialization Vector (IV) when parsing AuthEnvelopedData structures that use Authenticated Encryption with Associated Data (AEAD) ciphers such as AES-GCM. This can lead to a crash, causing a Denial of Service (DoS), or potentially allow for remote code execution.

9.8 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
