CVE-2026-80785

CVE-2026-80785 is a race condition in the Linux kernel's fbdev (framebuffer device) subsystem. The functions show_mode(), show_modes(), and store_mode() access fb_info->modelist and fb_info->mode without holding lock_fb_info(), while store_modes() takes that lock and frees the old modelist....

CVE-2026-80786

CVE-2026-80786 affects the Linux kernel fbdev (framebuffer) subsystem. The root cause is that user-invoked calls to fb_set_var() from sysfs and driver code paths were missing fbcon -related steps (checking mode-change feasibility, updating hardware state, and updating fbcon). Only the FBIOPUT_VSC...
