This repo contains a proof-of-concept for 📱🚀👑⚡, a deserialization vuln for local escalation of privilege to system_server in Android 10. This proof-of-concept only activates a privileged intent.
In ExternalVibration of ExternalVibration.java, there is a possible activation of an arbitrary intent due to unsafe deserialization. This could lead to local escalation of privilege to system_server with no additional execution privileges needed. User interaction is not needed for exploitation.
