CVE-2023-4234: Ofono: sms decoder stack-based buffer overflow remote code execution vulnerability within the decode_submit_report() function
First published: Wed Dec 20 2023(Updated: )
A flaw was found in ofono, an Open Source Telephony on Linux. A stack overflow bug is triggered within the decode_submit_report() 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_submit_report().
