CVE-2026-26104

Estado: ModificadaMedia (5.5)—

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.

El problema ocurre porque un método D-Bus privilegiado responsable de exportar metadatos de cifrado no realiza una verificación de política. Como resultado, los metadatos criptográficos sensibles pueden ser leídos y escritos en ubicaciones controladas por el atacante. Esto debilita las garantías de confidencialidad de los volúmenes de almacenamiento cifrados."
