CVE-2026-48137 is a critical-severity vulnerability rated 9.3/10 on the CVSS scale. 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.. EPSS estimates a 0.55% chance of exploitation in the next 30 days.
