The Red Hat security team deemed this advisory irrelevant for RHEL:6.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openssh-server package and not the openssh-server package as distributed by RHEL.
In ssh-agent in OpenSSH before 9.6, certain destination constraints can be incompletely applied. When destination constraints are specified during addition of PKCS#11-hosted private keys, these constraints are only applied to the first key, even if a PKCS#11 token returns multiple keys.
