There is no fixed version for RHEL:9 kernel-rt-debug-modules-extra.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug-modules-extra package and not the kernel-rt-debug-modules-extra 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).
