CVE-2026-4416 describes an Insecure Deserialization vulnerability affecting the Performance Library component of Gigabyte Control Center. This flaw allows authenticated local attackers to escalate privileges by sending a malicious serialized payload to the EasyTune Engine service. The vulnerability affects versions 0 through 25.12.31.01 and has been addressed in version 25.12.31.01.
CVE-2026-4416 affects the Performance Library component within Gigabyte Control Center, specifically the EasyTune Engine. This insecure deserialization vulnerability allows authenticated local attackers to send malicious serialized payloads to the EasyTune Engine service. Successful exploitation could lead to privilege escalation, enabling the attacker to gain unauthorized access to system resources or execute code with elevated privileges. The vulnerability's severity is rated as 7.8 on the CVSS scale, indicating a significant risk. Updating the software is crucial to mitigate this risk, especially in environments where security is paramount.
This vulnerability requires the attacker to have local access to the system and valid authentication credentials. The attacker must be able to send a malicious serialized payload to the EasyTune Engine service. The complexity of the attack can vary depending on the attacker's skill and the specific system configurations. The vulnerability is exploited by leveraging the way the EasyTune Engine service deserializes incoming data, allowing for arbitrary code execution. The lack of proper data validation during deserialization is the root cause of the vulnerability.

The recommended solution is to update Gigabyte Control Center to version 25.12.31.01 or later. This update includes the fix for the insecure deserialization vulnerability. In the meantime, restrict access to the EasyTune Engine service to authorized users only and monitor the system for suspicious activity. Implementing security policies that limit user privileges and applying the principle of least privilege can also help reduce the potential impact of this vulnerability. Regularly reviewing and strengthening existing security practices is essential to prevent future attacks.
