How to fix?

Upgrade Centos:9 kernel-abi-stablelists to version 0:5.14.0-503.11.1.el9_5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-abi-stablelists package and not the kernel-abi-stablelists package as distributed by Centos. See How to fix? for Centos: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.
