Executive Summary

CVE-2026-4416 is an insecure deserialization vulnerability in the Performance Library component of the Gigabyte Control Center. It allows an authenticated local attacker to send a malicious serialized payload to the EasyTune Engine service.

Exploiting this vulnerability results in privilege escalation, meaning the attacker can gain higher system privileges than originally granted.

Impact Analysis

This vulnerability can impact you by allowing an attacker with local authenticated access to escalate their privileges on your system.

  • The attacker can gain higher system privileges, potentially compromising system confidentiality, integrity, and availability.
  • The attack requires only low privileges and no user interaction, making it easier to exploit once local access is obtained.
Mitigation Strategies

The immediate step to mitigate this vulnerability is to update the Performance Library component of the Gigabyte Control Center to version 25.12.31.01 or later.

Compliance Impact

The provided information does not specify how CVE-2026-4416 affects compliance with common standards and regulations such as GDPR or HIPAA.
