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).
