Serious security flaws that could give attackers complete access to a phone's data have been found in software used on tens of millions of Android devices.
The issue affects Qualcomm processors, which are found in about 900 million Android based devices.
However, there is no evidence of the vulnerabilities currently being used in attacks by cyber criminals.
Affected devices included:
- BlackBerry Priv and Dtek50
- Blackphone 1 and Blackphone 2
- Google Nexus 5X, Nexus 6 and Nexus 6P
- HTC One, HTC M9 and HTC 10
- LG G4, LG G5, and LG V10
- New Moto X by Motorola
- OnePlus One, OnePlus 2 and OnePlus 3
- US versions of the Samsung Galaxy S7 and Samsung S7 Edge
- Sony Xperia Z Ultra
Qualcomm has also distributed the security fixes to phone makers and operators. However, it is not clear how many of those companies have issued updates to customers' phones.
Checkpoint has created a free app called QuadRooter Scanner that can be used to check if your device is affected.
If you own one of these devices, contact whoever sold this to you and ask them about getting the security fix.
