How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream udisks2-debugsource package and not the udisks2-debugsource package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A flaw was found in the udisks storage management daemon that allows unprivileged users to back up LUKS encryption headers without authorization. The issue occurs because a privileged D-Bus method responsible for exporting encryption metadata does not perform a policy check. As a result, sensitive cryptographic metadata can be read and written to attacker-controlled locations. This weakens the confidentiality guarantees of encrypted storage volumes.
