Attack-Flow Graph

Executive Summary

This vulnerability exists in the onUidImportance function of DisassociationProcessor.java, where improper input validation allows an application to retain companion application privileges even after disassociation. This means that an app could keep elevated privileges it should have lost, potentially leading to local escalation of privilege without needing any additional execution privileges. Exploitation requires user interaction.

Impact Analysis

If exploited, this vulnerability could allow a local attacker to escalate their privileges on the device without needing extra execution privileges. This could lead to unauthorized access or control over certain application privileges that should have been revoked, potentially compromising device security.
