CVE-2010-4012
Race condition in Apple iOS 4.0 through 4.1 for iPhone 3G and later allows physically proximate attackers to bypass the passcode lock by making a call from the Emergency Call screen, then quickly pressing the Sleep/Wake button.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
