This is achieved by sending a malicious IOCTL (Input/Output Control) request, which triggers the `ZwTerminateProcess()` function at the kernel level. This capability can be used to disable security software, such as Antivirus or Endpoint Detection and Response (EDR) systems.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
