Kernel imports (6)

Kernel-mode APIs resolved from the Import Address Table of mspqm.sys, ranked by exploitation relevance.

API	Risk	Why it matters
IofCompleteRequest	low	Standard kernel API - generally benign
ExAllocatePoolWithTag	low	Standard kernel API - generally benign
KeInitializeEvent	low	Standard kernel API - generally benign
ExFreePool	low	Standard kernel API - generally benign
IoCreateDevice	low	Standard kernel API - generally benign
IoDeleteDevice	low	Standard kernel API - generally benign

IOCTL dispatch codes (2)

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.

Code	Severity	Transfer	Description
0x002200F0	medium	METHOD_BUFFERED	FILE_DEVICE_UNKNOWN Function #60
0x00340388	medium	METHOD_BUFFERED	FILE_DEVICE_DISK Function #226

Exploit mitigations

Control Flow Guard	Enabled
ASLR	Enabled
DEP	Enabled
Integrity check	Not enforced
Mitigation score	80 / 100

CFG Enabled - Control Flow Guard is active - indirect calls are validated against a bitmap of valid targets at runtime.
ASLR Enabled - Address Space Layout Randomization is active - base address is randomized on each load.
DEP/NX Enabled - Data Execution Prevention is active - non-executable pages cannot be executed.
Unsigned - The driver is not digitally signed. It requires test signing mode or a bootloader exploit to load on 64-bit Windows.
