CVE-2026-4416
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Performance Library component of Gigabyte Control Center has an Insecure Deserialization vulnerability. Authenticated local attackers can send a malicious serialized payload to the EasyTune Engine service, resulting in privilege escalation.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Performance Library component in Gigabyte Control Center contains an insecure deserialization vulnerability in the EasyTune Engine service. Authenticated local attackers can send specially crafted malicious serialized payloads to the service, bypassing normal execution flow to achieve privilege escalation from a standard user account to elevated privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if EasyTune Engine service is installedOpen Windows Services (services.msc) and look for a service named 'EasyTune Engine' or check Programs and Features for Gigabyte Performance Library or Gigabyte Control Center componentsAffected if The service or Gigabyte Performance Library component is present on the system
-
Determine the installed version of Gigabyte Performance LibraryCheck the file version of the Performance Library DLL or executable. Common paths include C:\Program Files\Gigabyte\Performance Library\ or check the EasyTune Engine service executable properties in Windows ServicesAffected if Unable to determine version or version shown is below 25.12.31.01
-
Verify the EasyTune Engine service statusOpen Services (services.msc), locate the EasyTune Engine service, and check if its Status is 'Running'Affected if The service is currently running and the installed version is below 25.12.31.01
-
Confirm version is within affected rangeCompare the installed version number to the affected range: versions prior to 25.12.31.01 are vulnerableAffected if Installed version is 25.12.31.00 or lower (any version before 25.12.31.01)
You are affected if the Gigabyte Performance Library/EasyTune Engine service is installed with a version lower than 25.12.31.01 and the service is running on your system.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data25.12.31.01
Apply vendor-provided patches for Gigabyte Control Center when released. Until then, restrict local access to trusted authenticated users only and monitor the EasyTune Engine service for unusual serialized object traffic.
