How to fix?

There is no fixed version for Centos:7 sendmail-cf.

NVD Description

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

The sm_close_on_exec function in conf.c in sendmail before 8.14.9 has arguments in the wrong order, and consequently skips setting expected FD_CLOEXEC flags, which allows local users to access unintended high-numbered file descriptors via a custom mail-delivery program.
