CVE-2026-116487: NXP MCUXpresso SDK USB middleware out-of-bounds read in RNDIS

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.

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.
