How to fix?

Upgrade RHEL:9 kernel-abi-stablelists to version 0:5.14.0-284.48.1.el9_2 or higher.
This issue was patched in RHSA-2024:0448.

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 RHEL. See How to fix? for RHEL:9 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).
