This flaw, rated with a CVSSv3.1 score of 7.8 (High) and CVSSv4.0 score of 8.5 (High), allows authenticated local attackers to achieve kernel-level privileges. By sending specifically crafted IOCTL commands to the \u003ccode\u003eMyPortIO_x64.sys\u003c/code\u003e driver, which is bundled with the module, attackers can perform arbitrary read and write operations on physical memory. This provides a direct path to privilege escalation, enabling malicious actors to gain full control over the affected system. The vulnerability is critical for organizations using Gigabyte motherboards with GCC installed, as it allows a low-privileged user or malware to escalate privileges to kernel level.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn authenticated local attacker gains access to a system running Gigabyte Control Center.\u003c/li\u003e\n\u003cli\u003eThe attacker identifies the presence of the MBStorage DRAM lighting control module and its bundled driver, \u003ccode\u003eMyPortIO_x64.sys\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe attacker prepares specific IOCTL commands designed to exploit the Improper Access Control vulnerability in the \u003ccode\u003eMyPortIO_x64.sys\u003c/code\u003e driver.\u003c/li\u003e\n\u003cli\u003eThe attacker sends these crafted IOCTL commands to the \u003ccode\u003eMyPortIO_x64.sys\u003c/code\u003e driver.\u003c/li\u003e\n\u003cli\u003eDue to the improper access control, the driver executes the commands, allowing arbitrary read and write operations to physical memory.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the arbitrary physical memory access to inject malicious code or modify kernel structures.\u003c/li\u003e\n\u003cli\u003eThis manipulation grants the attacker kernel-level privileges on the compromised system.\u003c/li\u003e\n\u003cli\u003eThe attacker can then perform arbitrary actions with the highest system privileges.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-9492 grants authenticated local attackers kernel-level privileges, which is the highest level of access on a Windows system. This allows an attacker to take complete control of the affected device, bypassing security mechanisms, installing persistent malware, exfiltrating sensitive data, or causing system instability. For organizations, this means a compromised user account could be leveraged to gain administrative control over a workstation or server, leading to potential network-wide breaches and data loss.
