CVE-2025-11568
Full vulnerability record from the local CVENow database.
Description
A data corruption vulnerability has been identified in the luksmeta utility when used with the LUKS1 disk encryption format. An attacker with the necessary permissions can exploit this flaw by writing a large amount of metadata to an encrypted device. The utility fails to correctly validate the available space, causing the metadata to overwrite and corrupt the user's encrypted data. This action leads to a permanent loss of the stored information. Devices using the LUKS formats other than LUKS1 are not affected by this issue.

"value": "Una vulnerabilidad de corrupción de datos ha sido identificada en la utilidad luksmeta cuando se usa con el formato de cifrado de disco LUKS1. Un atacante con los permisos necesarios puede explotar esta falla escribiendo una gran cantidad de metadatos en un dispositivo cifrado. La utilidad no valida correctamente el espacio disponible, causando que los metadatos sobrescriban y corrompan los datos cifrados del usuario. Esta acción lleva a una pérdida permanente de la información almacenada. Los dispositivos que usan los formatos LUKS distintos de LUKS1 no se ven afectados por este problema."
