While an integer overflow in the nextScaffoldPart function on 32-bit platforms can potentially lead to denial of service (DoS) or, in rare cases, arbitrary code execution, the vulnerability is platform-specific, affecting only 32-bit architectures with particular handling of UINT_MAX and SIZE_MAX. Additionally, exploiting the overflow for arbitrary code execution would require precise manipulation of memory, making it a less likely attack vector. The primary risk of DoS, without guaranteed escalation to remote code execution, further justifies the moderate severity classification.", "threat_severity": "Moderate"}
