8.1 HIGH — CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H

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.

Affected configurations

• linux linux kernel (>= 6.2 < 6.6.140) • linux linux kernel (>= 6.7 < 6.12.90) • linux linux kernel (>= 6.13 < 6.18.32) • linux linux kernel (>= 6.19 < 7.0.9) • linux linux kernel 7.1
