Nordic nRF70/nRF71 Wi-Fi driver in Zephyr firmware: identifiers and CRA notes

Nordic nRF70/nRF71 Wi-Fi driver

Notes on this component

RENAMED since the ticket candidate list was written: at the pinned `v3.4.1` tag, `drivers/wifi/` in `sdk-nrf` has only an `nrf71/` subdirectory (`menuconfig WIFI_NRF71`), no `nrf70/` — `CONFIG_WIFI_NRF70` does not exist as a Kconfig symbol at this tag. This is the host-side driver SOURCE (`drivers/wifi/nrf71`); the firmware patch the chip itself runs is the separate `nordic-nrf70-wifi-fw` blob row, which this symbol does not by itself imply is present (a `.config`-only upload has no firmware file to pattern-match). Zephyr's own nRF70 driver (`drivers/wifi/nrf_wifi` in the Zephyr tree, not this one) carries CVE-2026-10664, an out-of-bounds write from an unchecked TWT flow count in a power-save event, fixed in Zephyr 4.5.0; it is filed against the Zephyr kernel and does not describe this driver. No advisory names this sdk-nrf driver as of 10 October 2026: none of the CVEs NVD lists from Nordic's own CVE Numbering Authority, nothing in GitHub's advisory database for sdk-nrf, nothing in NVD. It is source, not a binary, but it has no CPE, so there is no public identifier to match against: a vulnerability in it will not appear in a match here, and a maker has to watch Nordic's own security advisories for it.

Where it hides in a firmware SBOM

It is compiled into the kernel image when CONFIG_WIFI_NRF71 is y. It does not appear in west spdx output; the only trace is the .config file in your build directory.

The identifiers we assign

No PURL and no CPE are recorded for this row.

{version} is filled in from your build. The version is read from the version your SBOM already carries for it.

The SBOM check adds these identifiers to a component your build listed without them.

Honest gaps

Vendor: nordicsemiconductor.

This row has no CPE and no PURL, so feeds cannot be matched by identifier.

CRA notes

• List this component in your SBOM. Annex I, Part II (1): Identify and document components and vulnerabilities, including an SBOMKnow what is in your product. Identify and document its components and their vulnerabilities, including by producing a software bill of materials (SBOM) in a common machine-readable format that covers at least the top-level dependencies.
• Ship the version with no known exploitable vulnerabilities at release. Annex I, Part I (2(a)): Made available without known exploitable vulnerabilitiesWhen you place a release on the market, it must not ship with known vulnerabilities that can be exploited in your product. "Exploitable" means an attacker could effectively use it under practical operating conditions (Article 3(41)), not only in theory or in a lab. The Commission's draft guidance (C(2026) 5252, points 231 to 237; a draft, not binding) gives three ways a vulnerability is "known". One: it is listed in a relevant public vulnerability database, such as the European vulnerability database (EUVD) or another prominent one. Two: you learned of it from information that is not public, for example a security researcher's coordinated disclosure or your own testing and analysis; a vulnerability you know about and have not disclosed still counts. Three: it has been publicly and prominently reported in reliable media, whether specialist security publications or general news. A report is not yet proof: it does not by itself mean the vulnerability can be exploited in practice or applies to your product, so investigate promptly and confirm whether it does. A limited time may pass between the first report and that confirmation. If a vulnerability becomes known shortly before release, you decide from your cybersecurity risk assessment whether the release can go out or the vulnerability must be fixed first. Weigh its severity, exploitability and potential impact, and the risks to the product once in use; you may also weigh the risks of delaying the release, for example because it fixes other exploitable vulnerabilities. After release, the Part II vulnerability handling requirements still apply. Check your components against vulnerability databases before each release, and fix or justify what you find.
