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