Details

In updateCapabilities of ConnectivityService.java, there is a possible incorrect network state determination due to a logic error in the code. This could lead to biasing of networking tasks to occur on non-VPN networks, which could lead to remote information disclosure, with no additional execution privileges needed. User interaction is not needed for exploitation.
