What's Really New In Android 4.4.1 And 4.4.2
Bug: SMS DOS
A particularly unnerving SMS vulnerability, by which Nexus phones could be rebooted or denied cellular connectivity, was squashed with the 4.4.2 update. The bug, which Cody detailed here is essentially a denial-of-service vulnerability by which flash messages (messages that display immediately on screen, typically used for emergency notifications) pile up and cause some unsavory side-effects. Over a year since it was first reported to the Android Security team by Bogdan Alecu, the bug is finally fixed, as confirmed by JR Raphael.

La verdad, no tengo ni idea de quién es el Raphael ese, pero los de AP suelen ser muy fiables
