Exploitability: 2.8 / Impact: 5.2

Description
In the Linux kernel, the following vulnerability has been resolved:
HID: playstation: Clamp num_touch_reports
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.
