Name of the Vulnerable Software and Affected Versions Android versions Android-12

Description The issue is related to a possible bypass of user interaction requirements in the onCreate method of AllowBindAppWidgetActivity.java due to unclear UI. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is required for exploitation.

Recommendations For Android version Android-12, consider implementing clearer UI guidelines in the AllowBindAppWidgetActivity to prevent bypassing user interaction requirements as a temporary workaround until a patch is available. Restrict access to sensitive features that could be exploited through this bypass to minimize the risk of local escalation of privilege.
