> The HID driver raw_event callback runs before HID core validates the
> received report length. aqc_raw_event() reads device-specific status
> fields at fixed offsets, including multi-byte values, without checking
> that the received buffer contains the complete report. A truncated status
> report can therefore cause out-of-bounds reads and update hwmon state with
> data beyond the received report.
>
> Reject status reports shorter than the length derived from their report
> descriptor before accessing any fields. Commit 47669bec44fe ("HID: asus:
> refactor the two workqueues and init sequence") added equivalent raw-event
> length validation to hid-asus.
