How to fix?

Upgrade Centos:8 kernel-core to version 0:4.18.0-147.5.1.el8_1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-core package and not the kernel-core package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow.
