How to fix?

Upgrade Centos:7 kernel-kdump to version 0:3.10.0-1062.el7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-kdump package and not the kernel-kdump package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The alarm_timer_nsleep function in kernel/time/alarmtimer.c in the Linux kernel through 4.17.3 has an integer overflow via a large relative timeout because ktime_add_safe is not used.
