Vulnerability Title
Udisks: missing authorization check allows unprivileged users to restore luks headers via udisks d-bus api
Source: NVD (National Vulnerability Database)
Vulnerability Description
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.
