CVE-2026-26104 – Udisks: missing authorization check allows unprivileged users to back up luks headers via udisks d-bus api

CVE ID : CVE-2026-26104

Published : Feb. 25, 2026, 10:51 a.m. | 16 minutes ago

Description : 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.

Severity: 5.5 | MEDIUM
