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

Description The issue is related to improper input validation in the isSubmittable and showWarningMessagesIfAppropriate functions of WifiConfigController.java and WifiConfigController2.java. This could lead to a possible insecure WiFi configuration, resulting in remote information disclosure without requiring additional execution privileges. User interaction is not necessary for exploitation.
