Exploit mitigations

Control Flow Guard	Not enabled
ASLR	Not enabled
DEP	Not enabled
Integrity check	Not enforced
Mitigation score	0 / 100

• No CFG - Control Flow Guard is not enabled. Indirect call targets are not validated, making the driver susceptible to control flow hijacking via corrupted function pointers or vtables.
• No ASLR - ASLR is disabled. The driver loads at a predictable address, enabling reliable exploitation of memory corruption vulnerabilities.
• No DEP - DEP is disabled. Data pages are executable, allowing shellcode execution from stack/heap buffers.
• Unsigned - The driver is not digitally signed. It requires test signing mode or a bootloader exploit to load on 64-bit Windows.
