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 · unedited
In EmberZNet v9.0.2 and earlier, a malformed GetProfileResponse message can trigger out-of-bounds reads while iterating interval entries and terminate the process. These messages must come from a device that has already joined the network, and no information leakage back to the sender was observed. Only devices supporting the Simple Metering cluster may be impacted.

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 confidence

Out-of-bounds read vulnerability in EmberZNet's Simple Metering cluster GetProfileResponse message handling. A malformed GetProfileResponse with malicious interval entry data triggers the out-of-bounds read during iteration, causing process termination (DoS). Exploitation requires an already-authenticated device on the network.

MitigationUpdate EmberZNet to a version beyond 9.0.2 when the vendor patch becomes available; apply network segmentation to limit Simple Metering cluster exposure to trusted devices only.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify EmberZNet version
    Locate the EmberZNet stack version in your deployed firmware or software build. This information is typically found in firmware metadata, release notes, or the Silabs stack initialization logs.
    Affected if Version is 9.0.2 or lower
  2. Confirm Simple Metering cluster usage
    Inspect your application or device configuration to determine whether the Simple Metering cluster (Zigbee cluster 0x0700) is implemented and actively processing GetProfileResponse messages.
    Affected if Simple Metering cluster is enabled and processing GetProfileResponse messages
  3. Assess network accessibility
    Review network topology and access controls to check whether devices exposing Simple Metering cluster are reachable from network segments containing the authenticated but potentially compromised devices.
    Affected if Authenticated devices on less-trusted network segments can reach Simple Metering cluster endpoints

You are affected if your EmberZNet version is 9.0.2 or lower and the Simple Metering cluster with GetProfileResponse handling is active on your network.

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 data
Upgrade available Upgrade to a release after 9.0.2
Interim mitigation

Update EmberZNet to a version beyond 9.0.2 when the vendor patch becomes available; apply network segmentation to limit Simple Metering cluster exposure to trusted devices only.
