CVE-2018-19322
CVE-2018-19322
In short
GIGABYTE system drivers allow unauthorized reading and writing to hardware ports, which attackers can exploit to gain administrator-level control of the computer.
Technical detail
The GPCIDrv and GDrv drivers in affected GIGABYTE applications expose I/O port read/write operations without proper access controls, enabling local privilege escalation to kernel level through direct hardware manipulation.
Summary generated and translated by AI from the official description.
The GPCIDrv and GDrv low-level drivers in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME GAMING ENGINE before 1.26, and OC GURU II v2.08 expose functionality to read/write data from/to IO ports. This could be leveraged in a number of ways to ultimately run code with elevated privileges.
