Once you are in the VPN tunnel all communications are routed through the
VPN tunnel. Security risk to work assets is relatively nil so long as
the device you are using is clean and free of exploits such as keyloggers.

This says nothing to the protection of the local wireless node
connection. The local node can be easily exploited or used by anyone
who is familiar with wifi tools. Your system, while connected through
the vpn tunnel (at least vpns I am familiar with) can not communicate
outside the tunnel as long as the vpn is active, so the active VPN
system should be relatively immune to attack from outside the tunnel.

But the communications via the VPN should be relatively secure.
