Description Robert Frohl 2023-07-18 07:23:21 UTC 
CVE-2023-38409

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).
