A set of four vulnerabilities named QuadRooter has been discovered by Check Point Researchers. Any of the vulnerabilities, if exploited gives an attacker privilege to gain root access to a device. Consequently, the attacker can modify system-level files, add or remove apps and access the screen, camera and microphone of the device.
QuadRooter affects only Android devices with Qualcomm chipset but Qualcomm chipsets account for about 80% of chipsets in the Android world making the vulnerabilities very prevalent.
QuadRooter scanner app has been released by Check Point to help users scan their device for the QuadRooter vulnerability.
QuadRooter can only be fixed by installing patches released by manufacturers to fix the issue.
