Information disclosure in UNISOC validationtools on Android 11 through 13 allows local users to read protected data without interaction. UNISOC has not published the affected function, protected resource, or operation that omits the permission check. A locally installed application can reach the exposed interface without additional execution privileges; the vendor reports confidentiality loss only.
