Kingston FURY CTRL RGB Control Software up to 2.0.66.0 ships a driver, NTIOLib_X64.sys, whose IOCTL handler is reachable without proper access control (CWE-782), per VulDB. It needs local access. No Kingston advisory, fixed version or public exploit was found.

_Summary, check and fix written by a model from the sources; labelled as such._
