CVE-2026-26103

Full vulnerability record from the local CVENow database.

Description

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.

El problema permite a un usuario local sin privilegios instruir al demonio udisks, propiedad de root, para sobrescribir metadatos de cifrado en dispositivos de bloque. Esto puede invalidar permanentemente las claves de cifrado y dejar los volúmenes cifrados inaccesibles. La explotación exitosa resulta en una condición de denegación de servicio a través de una pérdida de datos irreversible."
