GIGABYTE Multiple Products

CVE-2018-19322

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 this means for your business

  • It affects GIGABYTE Multiple Products. It matters if your company, or a supplier that handles your data, runs it.
  • Attackers are already using it. CISA added it to its list of flaws used in real attacks on 24 October 2022.
  • Ransomware gangs are known to have used it.
  • An attacker can use it only with access to the machine itself, with an ordinary user login, and without anyone at your company clicking anything.
  • FIRST's prediction model gives it a 2% chance of attack attempts being seen in the next 30 days, ranking above 77% of all known flaws.

What to do

  1. 1Check whether your company or your suppliers run GIGABYTE Multiple Products, and which version. The affected versions are listed further down this page.
  2. 2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
  3. 3Treat it as urgent. US federal agencies must fix it by 14 November 2022. That deadline does not apply to private companies, but it shows how seriously CISA takes it.
  4. 4Because attackers have used it, check the affected systems for signs of a break-in, not only for the update.
