Can you explain this vulnerability to me?
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.
