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.

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
