In the Linux kernel, the following vulnerability has been resolved:
hwmon: (lm90) Prevent integer overflow/underflow in hysteresis calculations
Commit b50aa49638c7 ("hwmon: (lm90) Prevent integer underflows of temperature calculations") addressed a number of underflow situations when writing temperature limits. However, it missed one situation, seen when an attempt is made to set the hysteresis value to MAX_LONG and the critical temperature limit is negative.
Use clamp_val() when setting the hysteresis temperature to ensure that the provided value can never overflow or underflow.
