Name of the Vulnerable Software and Affected Versions Android versions Android-11

Description The issue is related to a possible bypass of device admin settings due to unclear UI in the onBindViewHolder function of AppSwitchPreference.java. This could lead to local escalation of privilege, requiring user interaction for exploitation and user execution privileges. The problem is associated with errors in privilege management.

Recommendations For Android version Android-11, consider restricting access to the onBindViewHolder function of AppSwitchPreference.java to minimize the risk of exploitation until a patch is available. As a temporary workaround, ensure that device admin settings are clearly understood and managed to avoid potential bypasses.
