NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh-keycat package and not the openssh-keycat package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

In sshd in OpenSSH before 10.6, the value "none" for a configuration option is sometimes interpreted as a filename but was intended to mean that a feature is disabled.
