Specifically, it requires an unlikely scenario where the input passed to the function has a negative length (len < 0), which would typically not occur in well-formed applications. Moreover, while the impact includes denial of service (DoS), the conditions necessary for arbitrary code execution are non-trivial, requiring specific exploitation of memory corruption. Since it primarily leads to application crashes without an easily accessible attack vector for remote code execution, the risk is lower compared to higher-severity vulnerabilities that offer more direct pathways to exploitation.", "threat_severity": "Moderate"}
