Stingray SoC has six temperature sensor and those are configured, controlled and accessed to read temperature and update in DDR memory using m0 firmware. All six sensors has been given 4 bytes of memory in DDR to write temperature in millivolts. This thermal driver read temperature values from DDR because no direct access to sensors. Like this all temparature sensors are monitored and trips at critical temperature. If driver can't handle thermal runaways because of any unknown reason, then firmware in m0 Processor will handle.
