In the Linux kernel, the following vulnerability has been resolved:

fbdev: clear fb_info->mode before deleting a videomode

fb_set_var() can delete a mode from info->modelist when userspace

passes FB_ACTIVATE_INV_MODE through FBIOPUT_VSCREENINFO. The code

checks that the mode being deleted is not the current info->var and

that fbcon is not using it, but it does not check fb_info->mode.

fb_info->mode may still point into the modelist entry being deleted.

If the entry is freed, later mode sysfs reads through show_mode() can

dereference a stale pointer.

Clear fb_info->mode before calling fb_delete_videomode() when it

matches the mode being removed. (NVD)
