(Taiwan ODM) that ships with Control Center 3.0 and Flexicharger utilities on Clevo-chassis laptops (XMG, Eluktronics, EVOO, Origin PC, System76, Sager, and others). CVE-2022-37415 (CVSS 7.8) documents an out-of-bounds write vulnerability. The driver exposes arbitrary physical memory read via MmMapIoSpace, unrestricted I/O port read/write, arbitrary PCI configuration space read/write, and SMBus/I2C read/write. The device is created with IoCreateDevice (no DACL) and IRP_MJ_CREATE returns STATUS_SUCCESS unconditionally with zero caller validation. A public PoC exists by alfarom256.","Usecase":"Elevate privileges","Privileges":"kernel","OperatingSystem":"Windows
