CISA KEV Advisory
GIGABYTE Multiple Products Code Execution Vulnerability
The GPCIDrv and GDrv low-level drivers in GIGABYTE App Center, AORUS Graphics Engine, XTREME Gaming Engine, and OC GURU II 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.
Apply updates per vendor instructions.
Risk Analysis
This high-severity vulnerability in GIGABYTE's low-level drivers (GPCIDrv and GDrv) exposes functionality to read/write data from/to IO ports. This can be leveraged by an attacker to run code with elevated privileges. Its inclusion in CISA's KEV catalog and an EPSS score of 0.02884 confirm it as a known and actively exploited vulnerability.
This vulnerability is actively being exploited in the wild, as confirmed by CISA's KEV catalog. Exploitation could lead to running code with elevated privileges.
Users of GIGABYTE App Center, AORUS Graphics Engine, XTREME Gaming Engine, and OC GURU II should update their software and drivers to the latest secure versions. Restrict access to low-level driver functionality where possible.
Technical Analysis
CVE-2018-19322 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2018-19322 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
