CVE-2018-19321
7.8 · HIGH Actively ExploitedOverview
CVE-2018-19321 is a high-severity vulnerability affecting gigabyte aorus_graphics_engine. It was published on December 21, 2018 and has a CVSS 3.1 base score of 7.8 (HIGH). This vulnerability is listed in CISA's Known Exploited Vulnerabilities catalog, indicating active exploitation in the wild.
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical 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 and write arbitrary physical memory. This could be leveraged by a local attacker to elevate privileges.
Remediation
Check the references section for vendor advisories and patches from gigabyte. Update aorus_graphics_engine to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
