All the vulnerabilities the rooting apps uses to date were fixed in the security patches somewhere around 2018 January.īut there can be issues some manufacturers forgot to patch! What about them? So the scope of the vulnerabilities is highly decreasing. Why are the rooting apps not working anymore?Īs referenced in the Bulletins above, Google fixes a series of issues in Android every month.

Almost all of the apps mentioned above exploit this vulnerability. An example is the infamous Dirt圜0W vulnerability which was given the CVEID CVE-2016-5195, which plagued and still plague the older Linux kernels. The exploits/vulnerabilities that get discovered are given an CVEID, and then detailed in the CVE website, and fixed in the Android Security Bulletins. If some app requires root, the app executes that binary, and you see a prompt whether to allow or decline root access. And then they mount as read/write the directory named /system which houses the processes required to get the system running and the system apps, and place a binary named su in a place of the directory, namely /system/bin/su. All of them use exploits/vulnerabilities/loopholes in the Android OS to give themselves privileges reserved to the system apps or even the Android OS itself. There are quite a lot of rooting apps, KingRoot, KingoRoot, Z4Root, Root Genius, Universal Androot to name a few popular/used to be popular apps. (For example, the official KingoRoot site says that it can root Android Oreo which is completely wrong information) I had this question a few months ago, and I found this answer through some research, so I thought to share my research in this site by answering my question, considering the fake information online.
