CVE-2026-35344

The dd utility in uutils coreutils suppresses errors during file truncation operations by unconditionally calling Result::ok() on truncation attempts. While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directories caused by full disks or read-only file systems. This can lead to silent data corruption in backup or migration scripts, as the utility may report a successful operation even when the destination file contains old or garbage data.

Summary		(es) La utilidad dd en uutils coreutils suprime errores durante las operaciones de truncamiento de archivos al llamar incondicionalmente a Result::ok() en los intentos de truncamiento. Aunque su intención es imitar el comportamiento de GNU para archivos especiales como [SystemPath], la implementación de uutils también oculta fallos en archivos regulares y directorios causados por discos llenos o sistemas de archivos de solo lectura. Esto puede llevar a una corrupción silenciosa de datos en scripts de copia de seguridad o migración, ya que la utilidad puede informar una operación exitosa incluso cuando el archivo de destino contiene datos antiguos o basura.
