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).
