{"id":"CVE-2023-38409","details":"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).","modified":"2026-03-14T12:10:53.059013Z","published":"2023-07-17T22:15:09.540Z","related":["SUSE-SU-2023:3302-1","SUSE-SU-2023:3311-1","SUSE-SU-2023:3376-1"],"references":[{"type":"ADVISORY","url":"https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2.12"},{"type":"FIX","url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=fffb0b52d5258554c645c966c6cbef7de50b851d"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"6.2.12"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-38409.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
