The ene.sys driver in G.SKILL Trident Z Lighting Control through 1.00.08 exposes mapping and un-mapping of physical memory, reading and writing to Model Specific Register (MSR) registers, and input from and output to I/O ports to local non-privileged users. This leads to privilege escalation to NT AUTHORITYSYSTEM.
