Kerentanan Missing Authorization pada redhat enterprise linux, freedesktop udisks. Skor CVSS 3.1 7.1 (High) menurut redhat.com.

Deskripsi (NVD)

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.
