Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
HID: playstation: Clamp num_touch_reports<br />
<br />
A device would never lie about the number of touch reports would it?<br />
<br />
If it does the loop in dualshock4_parse_report will read off the end of<br />
the touch_reports array, up to about 2 KiB for the maximum number of 256<br />
loop iteraions. The data that is read is emitted via evdev if the<br />
DS4_TOUCH_POINT_INACTIVE bit happens to be set. Protect against this by<br />
clamping the num_touch_reports value provided by the device to the<br />
maximum size of the touch_reports array.
