How to fix?

Upgrade Centos:7 kernel-headers to version 0:3.10.0-1160.114.2.el7 or higher.

NVD Description

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

An issue was discovered in set_con2fb_map in drivers/video/fbdev/core/fbcon.c in the Linux kernel before 6.2.12. Because an assignment occurs only for the first vc, the fbcon_registered_fb and fbcon_display arrays can be desynchronized in fbcon_mode_deleted (the con2fb_map points at the old fb_info).
