CVE-2023-45896

ntfs3 in the Linux kernel through 6.8.0 allows a physically proximate attacker to read kernel memory by mounting a filesystem (e.g., if a Linux distribution is configured to allow unprivileged mounts of removable media) and then leveraging local access to trigger an out-of-bounds read. A length value can be larger than the amount of memory allocated. NOTE: the supplier's perspective is that there is no vulnerability when an attack requires an attacker-modified filesystem image.

Summary		(es) ntfs3 en el kernel de Linux anterior a 6.5.11 permite a un atacante físicamente próximo leer la memoria del kernel montando un sistema de archivos (por ejemplo, si una distribución de Linux está configurada para permitir montajes sin privilegios de medios extraíbles) y luego aprovechar el acceso local para activar una lectura fuera de los límites. Un valor de longitud puede ser mayor que la cantidad de memoria asignada. NOTA: la perspectiva del proveedor es que no hay vulnerabilidad cuando un ataque requiere una imagen del sistema de archivos modificada por el atacante.
