| Aspect | Risk | Mitigation | |--------|------|-------------| | Firmware upload | Malicious FW could corrupt controller | Driver should validate CRC. | | I2C access | Kernel read/write to arbitrary registers | Only exposed via HID reports; no direct user access. | | Driver signing | Unsigned driver blocked on x64 Windows | Only use Microsoft-signed or OEM-signed version. | | KMDF crashes | Buggy driver → BSOD | Ensure latest version from Windows Update. | | Chip | Max Touches | Resolution |
