CVE-2026-9143 Medium · 5.3 CWE-681 Jun 19, 2026

Incorrect Conversion between Numeric Types in NI grpc-device due to missing range checks in CodeGen

There is an incorrect conversion between numeric types vulnerability in NI grpc-device due to missing range checks in CodeGen. This may silently discard high bits if a size value exceeded the target type's range. This affects NI grpc-device 2.17.0 and prior versions.

CVE-2026-9142 Critical · 9.1 CWE-306 Jun 19, 2026

NI grpc-device Server: Insecure Default Credentials Without TLS

There is an insecure default credentials vulnerability in NI grpc-device when TLS configuration is not present and the server is bound beyond loopback. This may allow an unauthenticated user access to the server on the local network. This affects NI grpc-device 2.17.0 and prior versions.

CVE-2026-48141 High · 7.5 CWE-401 Jun 19, 2026

Memory leak in NI grpc-device BeginSidebandStream

There is a memory leak in NI grpc-device BeginSidebandStream that may result in denial of service due to memory exhaustion. This affects NI grpc-device 2.17.0 and prior versions.

CVE-2026-48140 Medium · 6.5 CWE-704 Jun 19, 2026

Unchecked enum cast vulnerability in NI grpc-device in BeginSidebandStream

There is an unchecked enum cast vulnerability in NI grpc-device BeginSidebandStream that may allow an attacker to trigger invalid enum states and undefined behavior, potentially resulting in a denial of service. Successful exploitation requires an attacker to supply a specially crafted message containing an out-of-range value. This affects NI grpc-device 2.17.0 and prior versions.

CVE-2026-48139 High · 7.5 CWE-476 Jun 19, 2026
