Summary

In threadx modules, there is protection upon thread creation checking if priority and preemption priority is not higher than txm_module_instance_maximum_priority, but in thread_priority_change and thread_preemption_change there is no check for it

Impact

thread can have higher priority than allowed and potentially create a denial of service
