Snapdragon is a set of system on a chip (SoC) semiconductor products premeditated and advertised by Qualcomm for mobile devices. The Snapdragon central processing unit (CPU) customs the ARM RISC instruction set, and a single Soc may comprise many CPU cores , a graphics processing unit (GPU), a wireless modem, and other software and hardware to upkeep phone’s GPS, camera, indication recognition and video.
The first Snapdragon creation to be made available to consumer device creators was the QSD8250, which was released in November 2007. It comprised the first 1 GHz processor for mobile phones.
A Qualcomm Snapdragon processor doesn’t just manage our mobile device’s features, it develops them. With hardware and software premeditated to boost each area of use, your processor can enhance virtually any mobile experience—quick and efficiently.
The researchers have not revealed full details about the failings , the short brief about the flaws is as follows:
- Qualcomm-related flaw (CVE-2016-0819):It has been described by the investigators as a logic bug that permits a small part of kernel memory to be interfered with after it is freed, making an info leakage and a Use After Free issue in Android.
- The flaw (CVE-2016-0805)is in Qualcomm chipset kernel method get_krait_evtinfo: The get_krait_evtinfo method returns an index into an array used by other kernel functions. With the aid of sensibly crafted input data, it is probable to generate a malicious index, causing a buffer overflow.
- Gaining root access: Using both the flaws together on susceptible devices, foes can gain root access on the device.
