  "title": "fbdev: Wrap user-invoked calls to fb_set_var() in helper",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  fbdev: Wrap user-invoked calls to fb_set_var() in helper  Handle fbcon during display updates in fb_set_var_from_user(). Check with fbcon if the mode change is possible, update hardware state and finally update fbcon. Update all callers.  Only the FBIOPUT_VSCREENINFO ioctl currently does all steps. Other mode-changes callers in sysfs and driver code are missing fbcon-related steps.  With the new helper, ps3fb and sh_mobile_lcdcfb no longer maintain fbcon state themselves.",
