What is CVE-2023-4234?

A vulnerability exists in the ofono open-source telephony software for Linux, specifically within the decode_submit_report() function. This stack overflow issue arises during the decoding of SMS messages, potentially allowing remote code execution through manipulation of inputs from compromised modems, malicious base stations, or through crafted SMS messages. Although a bound check is implemented in the decode_submit() function, it has not been carried over to decode_submit_report(), resulting in a security gap that can be exploited. Further details can be found in the related issue tracking report here.
