In the Linux kernel, the following vulnerability has been resolved: HID: roccat: bound device-supplied profile index kone_keep_values_up_to_date() and kone_profile_activated() use an 8-bit, device-supplied profile value as an index into the 5-element kone->profiles[] array without a range check. A malicious USB device claiming the Roccat Kone id can send a switch-profile event (or a startup_profile read at probe) with an out-of-range value and make the driver read out of bounds; the result is exposed via the actual_dpi sysfs attribute. Reject out-of-range indices in both paths. This was found with static analysis and confirmed with the KUnit test added in the following patch (KASAN: slab-out-of-bounds).
