Vulnerability details
The vulnerability allows an attacker with physical access to disclose out-of-bounds data.
The vulnerability exists due to an out-of-bounds read in the Roccat Kone HID driver's profile handling when processing a device-supplied profile index. An attacker with physical access can connect a malicious USB device claiming the Roccat Kone ID and send a switch-profile event or provide a startup profile value during probing to disclose out-of-bounds data.
The out-of-bounds read result is exposed through the actual_dpi sysfs attribute.
