## Overview

In the Linux kernel, the following vulnerability has been resolved:

HID: intel-thc-hid: intel-quickspi: bound GET_REPORT response to the caller buffer

quickspi_hid_raw_request() receives the caller's buffer length in len, but
quickspi_get_report() never sees it and copies the whole device-supplied
response into buf regardless:

    memcpy(buf, qsdev->report_buf, qsdev->report_len);

qsdev->report_len comes from the input report the touch controller returns,
while buf is sized to whatever the caller asked hidraw for through
HIDIOCGFEATURE or HIDIOCGINPUT.  A response larger than that overflows buf
with device-controlled content.

The intel-quicki2c sibling already passes the caller length down to
quicki2c_get_report() and validates the response against it before the
copy.  Do the same here.
