CVE-2026-116487 · Severity: medium · CVSS 4.6 · Published 2026-10-26

NXP's MCUXpresso SDK USB middleware implements Remote Network Driver Interface Specification (RNDIS) support for embedded devices. A malicious USB host can send specially crafted network configuration commands that trigger an out-of-bounds memory read, potentially exposing sensitive device memory contents to the attacker.

Vendors: [NXP](https://junglewise.ai/threats/vendors/nxp).

## Quick answers

**Is CVE-2026-116487 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-116487 being exploited in the wild.

**How severe is CVE-2026-116487?** Medium severity, with a CVSS score of 4.6, published 26 October 2026.

**Which products and versions are affected?** NXP MCUXpresso SDK USB middleware before 2.13.0.

**Is there a fix for CVE-2026-116487?** Yes: fixed in 2.13.0. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-116487 attacked?** It is attacked from the adjacent network, in a software library.

**Am I affected by CVE-2026-116487?** Check whether you run NXP MCUXpresso SDK USB middleware at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- Fixed in 2.13.0

## Technical details

The vulnerability exists in USB_DeviceCdcRndisSetCommand() function, which processes RNDIS SET messages without validating the informationBufferOffset parameter supplied by the USB host. An attacker can craft OID_GEN_CURRENT_PACKET_FILTER or OID_802_3_MULTICAST_LIST messages with an out-of-range offset to read arbitrary memory. This requires the host to send crafted USB packets but no authentication or user interaction.
