We can find this type of exploitation in any system with a component without permission check. In most cases, it was used in the system service. It was especially dangerous because the component was an Android component (system service) and it was not checked for permissions. As a result, an attacker could get root access to the device. This type of attack is called a Local Elevation of Privilege. The component without permission check was present in the system service of a device, and this component is used by all applications installed on the system. In other words, if an application is installed on the system, it can access the component without permission check.

Conclusion: Protecting against Local Elevation of Privilege vulnerabilities
Local Elevation of Privilege vulnerabilities are the basis of the vast majority of remote code execution vulnerabilities. The attacker would first gain access to a system using them, and then exploit any number of different vulnerabilities to achieve root access. Fortunately, Android is equipped with a number of features that can help protect against these types of attacks. One feature is called Android Verified Boot, which requires every application to be digitally signed before they're loaded onto the device. If an application is unauthorized or has been modified from its original state, Android Verified Boot will prevent it from being loaded onto your device. Another protection feature is the KNOX framework, which provides a secure method for users to receive and install updates on their devices. Because most applications on devices are verified by KNOX, they won't be able to install rogue updates like a malicious application would be able to do. To further protect devices against Local Elevation of Privilege vulnerabilities, Google's Play Protect (previously known as Google Mobile Security) scans all new apps installed on devices for malicious activity and blocks those apps from being installed if they show signs of suspicious intent. In addition, Google Play services also scans installed apps for security threats and installs updates remotely when necessary.
Impact of CVE-2019-2022: Local Elevation of Privilege
The purpose of the vulnerability is to get root access on a device. In most cases, it was used in the system service. The component without permission check was present in the system service of a device, and this component is used by all applications installed on the system. In other words, if an application is installed on the system, it can access the component without permission check.
This type of attack is called a Local Elevation of Privilege. The component without permission check was present in the system service of a device, and this component is used by all applications installed on the system. In other words, if an application is installed on the system, it can access the component without permission check.
As such, this vulnerability could be exploited to gain root access to a device and become fully authorized with privileges that are greater than those of any user account that exists for the device. It has been reported that these vulnerabilities were actively being exploited by cybercriminals.
