CVE-2026-48137
Untrusted pointer dereference in NI grpc-device sideband streaming API
Description
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.
