Denial of Service

Description

From IoControlCode 0x9c40a0c8, 0x9c40a0dc, 0x9c40a0e0, 0x9c40a0d8, 0x9c4060d4, 0x9c402004, 0x9c402088, 0x9c40208c, 0x9c4060d0, 0x9c4060cc, 0x9c4060c4, 0x9c402084, and 0x9c402000, a normal user can cause DoS due to the lack of validating SystemBuffer.

Reproduce

In the attached file DoS1.zip, there are DoS1.exe, DoS1.cpp, DGSetup_Home_BZNR.exe, and mydrivers64.sys. DoS1.exe is the PoC to cause DoS where DGSetup_Home_BZNR.exe which contains the vulnerable driver mydrivers64.sys is installed, and DoS1.cpp is the source code of DoS1.exe. To reproduce the issue, install DGSetup_Home_BZNR.exe and execute DoS1.exe. It is expected that the system will crash (BSOD) once DoS1.exe is executed.
