[PATCH 0/4] Fix error handling in HID device probe functions

[Guenter Roeck <linux@roeck-us.net>]

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
driver probe functions. 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() in affected hardware monitoring drivers.

----------------------------------------------------------------
Guenter Roeck (4):
      hwmon: (corsair-cpro) Stop device IO before calling hid_hw_stop
      hwmon: (gigabyte_waterforce) Stop device IO before calling hid_hw_stop
      hwmon: (nzxt-smart2) Stop device IO before calling hid_hw_stop
      hwmon: (nzxt-kraken3) Stop device IO before calling hid_hw_stop
