            Description

            According to documentation the maximum allowed length to request in RecvFrom service (SOCK_CMD_RECVFROM_REQ command) is 1472 byte. However, the current implementation accepts larger values and may crash the firmware during processing such an service.

            The implementation should check the request length according to the documented and allowed range and reject the service otherwise.
