Kernel-mode APIs resolved from the Import Address Table of RNDISMP.sys, ranked by exploitation relevance.
| API | Risk | Why it matters |
|---|---|---|
| MmMapLockedPagesSpecifyCache | critical | Highly dangerous - potential for arbitrary code execution, memory corruption, or process termination |
| RtlInitUnicodeString | low | Standard kernel API - generally benign |
| IofCompleteRequest | low | Standard kernel API - generally benign |
Control codes reachable through the driver dispatch routine. Codes tied to published exploit code are flagged, since they are the primary Bring Your Own Vulnerable Driver (BYOVD) entry points.
