CVE-2026-24881

A flaw was found in GnuPG. A remote attacker could exploit this vulnerability by sending a specially crafted Cryptographic Message Syntax (CMS) EnvelopedData message. This message, containing an oversized wrapped session key, can cause a stack-based buffer overflow in the gpg-agent component. Successful exploitation may lead to a denial of service and potentially remote code execution.
