  "title": "fbdev: clear fb_info-\u003Emode before deleting a videomode",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  fbdev: clear fb_info-\u003Emode before deleting a videomode  fb_set_var() can delete a mode from info-\u003Emodelist when userspace passes FB_ACTIVATE_INV_MODE through FBIOPUT_VSCREENINFO. The code checks that the mode being deleted is not the current info-\u003Evar and that fbcon is not using it, but it does not check fb_info-\u003Emode.  fb_info-\u003Emode 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-\u003Emode before calling fb_delete_videomode() when it matches the mode being removed.",
