How to fix?

Upgrade RHEL:9 keylime to version 0:6.5.2-6.el9_2 or higher.
This issue was patched in RHSA-2023:5080.

NVD Description

Note: Versions mentioned in the description apply only to the upstream keylime package and not the keylime package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw was found in the Keylime registrar that could allow a bypass of the challenge-response protocol during agent registration. This issue may allow an attacker to impersonate an agent and hide the true status of a monitored machine if the fake agent is added to the verifier list by a legitimate user, resulting in a breach of the integrity of the registrar database.
