    decode_deliver() function during the SMS decoding. It is assumed that the attack scenario is accessible
    from a compromised modem, a malicious base station, or just SMS. There is a bound check for this memcpy
    length in decode_submit(), but it was forgotten in decode_deliver(). (CVE-2023-2794)
