Name of the Vulnerable Software and Affected Versions Android versions prior to the fixed version

Description A logic error in the code of AppOpsService.java allows for a possible way to access location without a visible indicator. This issue could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not required for exploitation.
