Exploit mitigations

Control Flow Guard	Not enabled
ASLR	Not enabled
DEP	Not enabled
Integrity check	Not enforced
Mitigation score	5 / 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.
Expired Certificate - The driver is signed but the certificate has expired. Windows may still load it depending on revocation policy.
