NVD Description

Note: Versions mentioned in the description apply only to the upstream integritysetup package and not the integritysetup package as distributed by RHEL. See How to fix? for RHEL: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.
