Detailsinfo

A vulnerability was found in Red Hat Enterprise Linux 6/7/8/9/10 and classified as problematic. Affected by this issue is an unknown part of the component udisks Storage Management Daemon. The manipulation with an unknown input leads to a authorization vulnerability. Using CWE to declare the problem leads to CWE-862. The product does not perform an authorization check when an actor attempts to access a resource or perform an action. Impacted is integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at access.redhat.com. This vulnerability is handled as CVE-2026-26103 since 02/11/2026. The exploitation is known to be easy.
