• Air-gapped environments only: Camera Connect is deployed in completely isolated environments lacking any network connectivity or internet access. • No exposure to MMS streams: The vulnerability depends on processing crafted MMS streams, which cannot originate from external or internal network sources when the system is air-gapped. • Elimination of remote attack surface: Without any method for an attacker to deliver malicious media inputs, the vulnerability cannot be triggered remotely. • Strong reduction in exploitation risk: The combined absence of external media ingestion and unavailable network paths effectively neutralizes the integer underflow exploit, significantly reducing the likelihood of both denial-of-service and memory corruption scenarios.
