NVD Description

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

A flaw was found in the udisks storage management daemon that exposes a privileged D-Bus API for restoring LUKS encryption headers without proper authorization checks. The issue allows a local unprivileged user to instruct the root-owned udisks daemon to overwrite encryption metadata on block devices. This can permanently invalidate encryption keys and render encrypted volumes inaccessible. Successful exploitation results in a denial-of-service condition through irreversible data loss.
