Affected: Alpaquita:stream: linux-lts

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.

Ein Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um Sicherheitsmaßnahmen zu umgehen, Daten oder den Systemzustand zu manipulieren, Denial-of-Service-Zustände herbeizuführen oder andere, nicht näher spezifizierte Angriffe durchzuführen.
