Detailed vulnerability description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a race condition in the thermal zone device registration error path when handling a failed thermal zone device registration after the device has already been registered. A local user can hold a reference to the thermal zone device's kobject to cause a denial of service.
The issue arises if user space obtains a reference before the error path completes, which can lead to premature freeing of the associated thermal zone structure.
