CVE-2026-26104 (opens in a new tab)Amendment
The AlmaLinux security team deemed this advisory irrelevant for AlmaLinux:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libudisks2 package and not the libudisks2 package as distributed by AlmaLinux.
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.
