CVE-2024-22004
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDue to length check, an attacker with privilege access on a Linux Nonsecure operating system can trigger a vulnerability and leak the secure memory from the Trusted Application
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA length check vulnerability in the secure world allows an attacker with privileged access on a Linux Nonsecure OS to leak secure memory from a Trusted Application running in ARM TrustZone. This is a TrustZone isolation bypass where improper bounds checking on a memory operation permits read access to protected secure world memory from the Normal World.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the Google Nest Wifi device modelCheck the device model or product name through the device's web interface, administrative console, or system information file (e.g., /proc/device-tree/model, /sys/class/dmi/id/product_name)Affected if Device is NOT a Google Nest Wifi Pro, Point, or Router - if not one of these models, the CVE does not apply
-
Check the firmware versionRetrieve the installed firmware version through the device's administrative interface, boot logs, or version file (e.g., /etc/version, /proc/version, or via the device's API endpoint that reports firmware info)Affected if Firmware version is NOT exactly 24r1 - only version 24r1 is affected; earlier or later versions are not in the affected range
-
Assess privileged access on Linux Nonsecure sideReview system logs, process lists, or security audit records for any evidence of root or kernel-level compromise, unauthorized privileged accounts, or suspicious privileged processes on the nonsecure Linux OSAffected if Attacker ALREADY HAS privileged access (root/kernel) on the Linux Nonsecure OS - this is a required condition for exploiting the TrustZone isolation bypass
You are affected only if you have a Google Nest Wifi Pro, Point, or Router with firmware exactly at version 24r1 AND an attacker already has privileged access on the device's Linux Nonsecure operating system.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict privileged access on the Linux Nonsecure side; apply vendor-provided patches for the affected Trusted Application or TEE firmware; ensure proper TrustZone isolation boundaries are enforced.
