Updated

In the Linux kernel, the following vulnerability has been resolved:

hwmon: (nzxt-kraken3) Stop device IO before calling hidhwstop

Calling hidhwstop() does not stop the device IO. This results in a race condition between hidinputreport() and the point immediately following the execution of hiddeviceiostart() within the driver probe function. If the probe operation fails after "io start" has been initiated, this race condition will result in a UAF vulnerability.

Fix the problem by calling hiddeviceiostop() before calling hidhwstop().
