Researchers from a computer security firm have discovered a number of bugs, which are caused by weaknesses in processor chips of certain smartphones and which could provide complete access to hackers.

The study, which was conducted by experts from the firm Check Point, indicates that these bugs could affect up to 900 million Android phones which are produced by some of the biggest manufacturers of smartphones in the world.

The company has found out that this issue could occur due to vulnerabilities in the processor chips used by the US firm Qualcomm. These weaknesses permit attackers to introduce in certain smartphones, through a malicious app and once inside take full control of the device.

Fortunately, there has been no evidence yet that this issue has occurred on real phones and the company Qualcomm has already taken necessary steps to contain this issue.

The bugs are being called "Quadrooter" because they are interconnected between them and once the attacker gets access through these smartphone, it will have access to the "roots" of the phone. This is the most secure part of the operating system and once the attacker manages to control it, then it will have full control of the device.

The security firm has suggested that all users keep their phone's software updated so that they can download the respective patches which might help them to avoid giving access to potential attackers. In fact, the companies which were affected by these weaknesses are issuing updates with the appropriate patches in order to help users to be protected against potential attacks.
