In startLegacyVpnPrivileged of Vpn.java, there is a possible way to retrieve VPN credentials due to a protocol downgrade attack. This could lead to remote escalation of privilege if a malicious Wi-Fi AP is used, with no additional execution privileges needed. User interaction is not needed for exploitation.
