SandboxEscaper initially announced the release of the PoC code for the new year, but she decided to publicly disclose it two days after the Christmas day.
The expert warns of some limitations for the exploit code that may not work on some CPUs, for example, it could not work on systems based on a single CPU core.

“You can also use it to perhaps disable third-party AV software,” the expert explained.
Will Dormann, a security expert at CERT/CC, was able to successfully execute the exploit code on Windows 10 Home, build 17134. The expert confirmed that the exploit not always works.
Experts from BleepingComputer pointed out that the exploit code could cause a DoS condition.

SandboxEscaper said that she has reported the bug to the Microsoft Security Response Center (MSRC) once published.
SandboxEscaper disclosed another Windows zero-day in December,
Since August, SandboxEscaper has publicly dropped exploits for two Windows zero-day vulnerabilities forcing Microsoft to quickly address them to avoid its users being targeted by hackers.
