The latest news on August 8th, according to foreign media reports, Check Point, an information security research company, recently discovered four important security holes for Android phones using Qualcomm processors. These vulnerabilities regarding the expansion of user rights are called "Quadrooter" and its scope of influence is wide. More than 900 million Android devices worldwide will be affected.
According to Check Point, hackers are likely to use these vulnerabilities to induce users to install malicious applications, and to fully control the affected Android phones or tablets without requiring any special permission, including accessing user software data and controlling microphone microphones, etc. hardware.
It is reported that Google's own brand Nexus 5X, Nexus 6 and Nexus 6P, HTC's One M9 and HTC 10, and Samsung Galaxy S7 and S7 Edge may be affected by this loophole. The recently released BlackBerry DTEK50 is still not spared despite being called the "safest Android smartphone."
In response, a Qualcomm spokesperson stated that the company had already disclosed chip-level underlying code to many mobile phone manufacturers that had collaborated with Qualcomm for these vulnerabilities, and issued patch patches in April and July this year. Users will not be affected by this vulnerability as long as they follow up on Google’s Android security updates released on a monthly basis.
Since then, Google has confirmed that 3 of the 4 vulnerabilities issued by Check Point have been fixed in the latest Android monthly security update ( version details link ), and the remaining vulnerability will be resolved in the early September security update.
However, the media also stated that since Qualcomm has already disclosed the source code and solutions for the vulnerabilities, it is entirely feasible for responsible vendors to not have to wait for Google's updates and to release fixes for vulnerabilities.
