Описание
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.
Отчет
The Red Hat Product Security team has rated this vulnerability as Moderate. Exploitation requires local system access but no authentication or user interaction. A successful attack allows an unprivileged user to cause the udisks daemon to overwrite LUKS encryption headers, resulting in loss of data integrity and availability.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to a widespread installation base, or stability.
