CVE-2016-1802
CCCrypt in CommonCrypto in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1 mishandles return values during key-length calculations, which allows attackers to obtain sensitive information via a crafted app.
Does this matter?
Lower severity and a low EPSS score (1.25%). Track it; it rarely justifies an emergency change on its own.
