In getLocationCache of GeoLocation.java, there is a possible way to send a mock location during an emergency call due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
The product attempts to drop privileges but does not check or incorrectly checks to see if the drop succeeded.
