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. (NVD)
