HID: playstation: Clamp num_touch_reports
Published May 28, 2026

HIGHCVSS 3.1
EPSS 0.40%
Description
A device would never lie about the number of touch reports would it?
If it does the loop in dualshock4_parse_report will read off the end of the touch_reports array, up to about 2 KiB for the maximum number of 256 loop iteraions. The data that is read is emitted via evdev if the DS4_TOUCH_POINT_INACTIVE bit happens to be set. Protect against this by clamping the num_touch_reports value provided by the device to the maximum size of the touch_reports array.
