Its unclear if this high-rated flaw affects other iOS devices and those running on much newer versions of iOS.
This finally results in a temporarily deactivation of the passcode lock screen.
The researcher says that he informed Apples security team about this exploit on October 22nd 2015.
Its not exactly clear why the flaw was publicly disclosed now.
Apple has still not released a fix, which leaves your iPhones vulnerable.
It is possible that the bug could be patched by Apple in the upcoming iOS 9.3.
Apple has not yet commented on this.
