No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

There is an untrusted pointer dereference vulnerability in the NI grpc-device sideband streaming API that may allow an attacker to cause an arbitrary memory dereference, potentially resulting in remote code execution.  Successful exploitation requires an attacker  to supply a specially crafted Moniker protobuf message.  This affects NI grpc-device 2.17.0 and prior versions.
