What it is

The GPCIDrv and GDrv low-level drivers in GIGABYTE App Center, AORUS Graphics Engine, XTREME Gaming Engine, and OC GURU expose functionality to read and write arbitrary physical memory. This could be leveraged by a local attacker to elevate privileges.

What to do

1. Check whether you run it. Look for Multiple Products in your asset inventory, including appliances and cloud images. Stack check lists every exploited GIGABYTE CVE at once.
2. Apply the fix. Apply updates per vendor instructions.
3. If you can't patch today, take the affected service off the internet or restrict who can reach it, and check its logs for signs of compromise since 21 Dec 2018.
4. Get told next time. Email alerts when CISA adds a CVE for GIGABYTE.
