How to fix?

Upgrade Centos:8 cryptsetup-libs to version 0:2.3.3-4.el8_5.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cryptsetup-libs package and not the cryptsetup-libs package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

It was found that a specially crafted LUKS header could trick cryptsetup into disabling encryption during the recovery of the device. An attacker with physical access to the medium, such as a flash disk, could use this flaw to force a user into permanently disabling the encryption layer of that medium.
