Impact: Denial of Service
Description: From IoControlCode 0x22E008u, a normal user can cause null pointer dereference due to the lack of validating kernel handle before using ZwDuplicateObject.
Reproduce: In the attached file DoS.zip, there are DoS.exe, DoS.cpp, iwn4k3ek.exe, and PROCOBSRVESX.sys. DoS.exe is the PoC to cause DoS where iwn4k3ek.exe which contains the vulnerable driver PROCOBSRVESX.sys is installed, and DoS.cpp is the source code of DoS.exe. To reproduce the issue, install iwn4k3ek.exe and execute DoS.exe. It is expected that the system will crash (BSOD) once DoS.exe is executed. Password for attachment: DoS
