I get an error when launching an exploit CVE-2016-5195. The work of the exploit is completed, without getting root rights. I checked my phone for this vulnerability with make test, as a result I received that the phone is affected by this vulnerability. enter image description here

I will be grateful for the help.

Did you use this ADB Exploit specifically for Android ?

Because it Only Gains Root Access,... You need to install a Root Access Manager yourself...

After getting UID = 0 ( Root Access ) Push SU Binary & Super User Application to the device..

This repository demonstrates the vulnerability on vulnerable Android devices attached via ADB. It does not disable SELinux (see https://github.com/timwr/CVE-2016-5195/issues/9) or install superuser on the device.

You need to disable SE Linux Also...
