CISA added it to its Known Exploited Vulnerabilities catalog on 24 Oct 2022, 1403 days after it was published. It is known to be used in ransomware campaigns. It affects GIGABYTE Multiple Products.

What it is

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.

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.
