CVE-2026-116487: NXP MCUXpresso SDK USB Middleware before 2.13.0 RNDIS Out-of-Bounds Read

MediumCVSS 5.1 · v4.0—Proof of concept No fix recorded

Noroxi assessment

Priority: Monitor (action score 20/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.29% (FIRST EPSS).
  • Physical access to the device is required. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • No fixed version is recorded, but the references include a patch (commit or PR) link.

Low priority for now. See the fix and affected versions sections below.

Primary sources: NVD · CVE.org · FIRST EPSS

NXP MCUXpresso SDK USB middleware (mcuxsdk-middleware-usb) before 2.13.0 contains an out-of-bounds read vulnerability in USB_DeviceCdcRndisSetCommand() that trusts a host-supplied informationBufferOffset. A malicious USB host can send RNDIS SET messages for OID_GEN_CURRENT_PACKET_FILTER or OID_802_3_MULTICAST_LIST with an out-of-range offset to read and disclose device memory.
