Reproduce
In the attached file DoS.zip, there are DoS.exe, DoS.cpp, MaxAVPlusDM.exe, and MaxProc64.sys. DoS.exe is the PoC to cause BSOD where MaxAVPlusDM.exe which contains the vulnerable driver MaxProc64.sys is installed, and DoS.cpp is the source code of DoS.exe. To reproduce the issue, just install MaxAVPlusDM.exe and execute DoS.exe. It is expected that the system will crash (BSOD) once DoS.exe is executed.
