NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-core package and not the kernel-64k-debug-core package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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.
