The good news is that Qualcomm has since addressed this issue by sending out patches to their partners. However the bad news is that we can’t be sure when manufacturers will release it for their devices, but if you’re a Sony Xperia owner, Sony has since come forward with a statement promising that a fix is incoming.
According to Sony, “Sony Mobile takes the security and privacy of customer data very seriously. We are aware of the ‘Quadrooter’ vulnerability and are working to make the security patches available within normal and regular software maintenance, both directly to open-market devices and via our carrier partners, so timings can vary by region and/or operator.”
They also add that until the patch has been released, or just as a general safety precaution, that users should not download from third-party app stores. “Users can take steps to protect themselves by only downloading trusted applications from reputable application stores.”
