Impact: Denial of Service
Description: From IoControlCode 0x222018, there is no proper validation of the length of user-supplied data and pass it as the second parameter of memcpy, which will cause BSOD when a user gives null input.
Reproduce: In the attached file DoS2.zip, there are DoS2.exe, DoS2.cpp, iobit_malware_fighter_setup.exe, and ObCallbackProcess.sys. DoS2.exe is the PoC to cause DoS where iobit_malware_fighter_setup.exe which contains the vulnerable driver ObCallbackProcess.sys is installed, and DoS2.cpp is the source code of DoS2.exe. To reproduce the issue, install iobit_malware_fighter_setup.exe and execute DoS2.exe. It is expected that the system will crash (BSOD) once DoS2.exe is executed. Password for attachment: DoS2
