Two high-rated motherboard security vulnerabilities have been identified in Gigabyte Control Center, so come update your software along with me

As an owner of a Gigabyte motherboard, I am intimately familiar with the intricacies of the Gigabyte Control Center (GCC) app. We've had issues in the past, me and that particular program. Anyway, there's an even better reason to update it now, as the company has posted two separate advisories relating to a pair of particularly nasty security vulnerabilities.

Candidate number one is called CVE-2026-4415, and it scores an 8.1 out of ten on the CVSS scale. That's High, for those of you wondering. "The issue stems from insufficient input validation during file handling within the GCC software", says Gigabyte.

"When the pairing feature is enabled, an unauthenticated remote attacker with network access can write arbitrary files to any location on the underlying operating system."

Yep, that sounds bad. The vulnerability affects GCC versions 25.07.21.01 and earlier, with the more recent versions plugging the gap. "Customers are strongly advised to upgrade to the latest GCC version immediately", says Gigabyte. I will, thanks very much.

The second issue scores slightly lower on the CVSS scale (7.8, which is still classed as High), but is still well worth an update to fix. CVE-2026-4416 is related to GCC's EasyTune Engine Service, and "allows a local malicious actor to execute arbitrary code with system privileges, leading to Local Privilege Escalation."

So, depending on your network setup and who has local access to your PC, it doesn't seem quite as bad as the first issue. Still, a security hole identified is a security hole worth plugging, and this one is also fixed by the very latest version of Gigabyte Control Center.

Motherboard software like GCC is very easy to forget about after its been setup. Even if you're not running a Gigabyte mobo, I'd say it's worth having a check of whatever motherboard software package is currently installed, and making sure everything is ship-shape and up-to-date. Better safe than sorry, as my dear old mother used to say.
