CWE-782Published: July 13, 2026· Updated: Jul 14, 2026
Official Description
The MBStorage DRAM lighting control module within Gigabyte Control Center (GCC) developed by GIGABYTE Technology has an Improper Access Control vulnerability. Authenticated local attackers can send specific IOCTL commands through the driver MyPortIO_x64.sys bundled with the module, thereby arbitrarily reading and writing physical memory and obtaining kernel-level privileges.
Technical Analysis
CVE-2026-9492 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
