Today researchers at security firm Check Point have revealed that over 900 million Android running smartphones and tablets that use Qualcomm chipset have been affected by a new flaw 'QuadRooter'. The flaw is basically a set of four vulnerabilities affecting nearly a billion android devices. The list of the devices that got affected includes the Galaxy S7 flagship and also the BlackBerry DTEK50 which company claims is "the world's most secure android smartphone."
The chip maker Qualcomm has already notified about the vulnerabilities - found in the company's software drivers - back in April this year. The chipmaker reported that they have fixed all the flaws and patches has started reaching over to customers. Out of four vulnerabilities 3 have been already fixed in recent Android monthly security update and the one remaining will be resolved in the September update.
The security firm CheckPoint has released a free QuadRooter Scanner app using which you can confirm whether these vulnerabilities exist on your device or not.
