Allele Security Alert
ASA-2018-00101, CORE-2018-0007, CVE-2018-19321
Drivers allow non-privileged user arbitrary read/write access to physical memory
GIGABYTE APP Center

OC GURU II
GIGABYTE APP Center v1.05.21 and previous
AORUS GRAPHICS ENGINE v1.33 and previous
XTREME GAMING ENGINE v1.25 and previous

Proof of concept
Default installation allows non-privileged user processes (even running at LOW INTEGRITY) to get a HANDLE and issue IOCTL codes to these drivers.
Both GPCI and GIO expose functionality to read/write arbitrary physical memory, allowing a local attacker to take complete control of the affected system.
