In the Linux kernel, the following vulnerability has been resolved:
hwmon: (corsair-cpro) Stop device IO before calling hid_hw_stop
Calling hid_hw_stop() does not stop the device IO. This results in a race condition between hid_input_report() and the point immediately following the execution of hid_device_io_start() 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 hid_device_io_stop() before calling hid_hw_stop().
