En handle_to_path(), solo se asignan 12 bytes de memoria para el miembro de la estructura file_handle->f_handle, lo que provoca un acceso fuera de los l\u00edmites al acceder al miembro parent_block de la estructura isofs_fid en isofs, ya que acceder a parent_block requiere al menos 16 bytes de f_handle. Aqu\u00ed, fh_len se utiliza para confirmar indirectamente que el valor de handle_bytes es mayor que 3 antes de acceder a parent_block.
