Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to an integer overflow/underflow in hysteresis calculations in the Linux kernel's hwmon component, specifically in the lm90 module. This occurs when setting the hysteresis value to MAX LONG and the critical temperature limit is negative. The problem was addressed by using the clamp val() function to prevent overflow or underflow when setting the hysteresis temperature.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
