CVE-2021-47098

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.
