Quadrooter vulnerability affects nearly 1 billion Snapdragon powered Android devices
Qualcomm says that between April and July, it fixed all of the flaws and sent out patches to partners, customers, and those in the open source community. Those patches have been included in the monthly security update sent out by Google to Nexus models, and rolled out by other manufacturers to their own phone and tablet creations.
Because one of the patches wasn't ready in time to be included in the August update, one of the remaining flaws remains vulnerable. That patch is expected to be sent out with the September update that will go out just after next month starts. Since Qualcomm has sent out patches directly to its manufacturing partners, some of them could send out the the last fix before Google's September update.
According to Michael Shaulov, head of mobility product management at Check Point, "No-one at this point has a device that's fully secure. That basically relates to the fact that there is some kind of issue of who fixes what between Qualcomm and Google."
