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."},{"lang":"es","value":"Se encontró una falla en el demonio de gestión de almacenamiento udisks que expone una API D-Bus privilegiada para restaurar los encabezados de cifrado LUKS sin las comprobaciones de autorización adecuadas. 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.
