How to fix?

There is no fixed version for RHEL:10 ceph-base.

NVD Description

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

A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.
