All Android devices powered by Qualcomm processors are susceptible to malicious attacks due to "Quadrooter" flaws. The vulnerability allows a malicious app to gain root access to the phone, giving it full control of the device and the information stored on it. All of the 2016 flagship smartphones are vulnerable to the Quadrooter flaws - even the QTEK50 which Blackberry is touting as the "most secure Android smartphone." Qualcomm has been aware of the issue and has supplied fixes to the flaws to its manufacturer partners, but there is no indication that any of them have released the fixes to their devices yet. Google has already released a fix for three of the Quadrooter flaws in previous security updates, but the final fourth flaw will not be patched until the September Android security update is released.
