Note: Versions mentioned in the description apply only to the upstream gnupg2 package and not the gnupg2 package as distributed by Centos.
In GnuPG before 2.5.17, a crafted CMS (S/MIME) EnvelopedData message carrying an oversized wrapped session key can cause a stack-based buffer overflow in gpg-agent during PKDECRYPT--kem=CMS handling.
