What it is

A vulnerability exits in driver snxpsamd.sys in SUNIX Serial Driver x64 - 10.1.0.0, which allows low-privileged users to read and write arbitary i/o port via specially crafted IOCTL requests .

These signed drivers can also be used to bypass the Microsoft driver-signing policy to deploy malicious code.
