Summary
AppOps appears to suppress MONITOR_HIGH_POWER_LOCATION op inappropriately with respect to location foreground services
Details

In onUidStateChanged of AppOpsService.java, there is a possible way to access location without a visible indicator due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
