CVE-2026-4416: CWE-502 Deserialization of untrusted data in GIGABYTE Performance Library
CVE-2026-4416 is a high-severity vulnerability in the Performance Library component of the Gigabyte Control Center. It involves insecure deserialization of untrusted data, allowing authenticated local attackers to send malicious serialized payloads to the EasyTune Engine service. Successful exploitation can lead to privilege escalation on the affected system. There is no information about an available patch or vendor advisory at this time. The vulnerability requires local authentication and does not involve user interaction.
AI Analysis
Technical Summary
The Performance Library component of Gigabyte Control Center contains an insecure deserialization vulnerability (CWE-502). Authenticated local attackers can exploit this by sending crafted serialized data to the EasyTune Engine service, resulting in privilege escalation. The CVSS v4.0 base score is 8.5, reflecting high severity with low attack complexity and no user interaction required. The vulnerability affects version 0 (likely indicating initial or unspecified versions). No patch or official remediation guidance is currently available.
Potential Impact
Exploitation of this vulnerability allows an authenticated local attacker to escalate privileges on the affected system by leveraging insecure deserialization in the EasyTune Engine service. This could lead to unauthorized access to higher-privilege functions or system components. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local access to trusted users only and monitor for suspicious activity related to the EasyTune Engine service. Avoid running the affected software with elevated privileges where possible.
