Description
In the Linux kernel, the following vulnerability has been resolved:
thermal: core: Fix thermal zone device registration error path
If thermal_zone_device_register_with_trips() fails after registering a thermal zone device, it needs to wait for the tz->removal completion like thermal_zone_device_unregister(), in case user space has managed to take a reference to the thermal zone device's kobject, in which case thermal_release() may not be called by the error path itself and tz may be freed prematurely.
Add the missing wait_for_completion() call to the thermal zone device registration error path.
