The wireless driver for the Android One (sprout) devices has a bad copy_from_user in the handling for the wireless driver socket private read ioctl IOCTL_GET_STRUCT with subcommand PRIV_CMD_SW_CTRL. This ioctl is permitted for access from the untrusted-app selinux domain, so this is an app-to-kernel privilege escalation from any app with android.permission.INTERNET.
