|---|---|
| Product | Multiple Products |
The 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 and write arbitrary physical memory. This could be leveraged by a local attacker to elevate privileges.
Required action
Apply updates per vendor instructions.
US federal civilian agencies were required to act by 14 November 2022 under BOD 22-01. The deadline is a compliance date, not a measure of severity — it says nothing about how dangerous the flaw is to anyone else.
Ransomware
CISA records this vulnerability as having been used in ransomware campaigns. That is a confirmed observation, not an assessment of likelihood.
