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.
