Vulnerability details
The vulnerability allows a local user to cause memory corruption.
The vulnerability exists due to an out-of-bounds write in the quickspi_get_report() function of the intel-quickspi HID component when copying a device-supplied GET_REPORT response into a caller-provided buffer. A local user can request an input or feature report through hidraw with a buffer smaller than the returned response to cause memory corruption.
