CVE-2026-26104: Freedesktop Udisks

Medium severity, CVSS 5.5. EPSS: 0.1% chance of exploitation in the next 30 days.

A flaw was found in the udisks storage management daemon that allows unprivileged users to back up LUKS encryption headers without authorization. The issue occurs because a privileged D-Bus method responsible for exporting encryption metadata does not perform a policy check. As a result, sensitive cryptographic metadata can be read and written to attacker-controlled locations. This weakens the confidentiality guarantees of encrypted storage volumes.
