CVE-2026-47154: CWE-125: Out-of-bounds Read in Silicon Labs EmberZNet
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.
AI Analysis
Technical Summary
In EmberZNet versions up to and including 9.0.2, a malformed GetProfileResponse message can cause out-of-bounds reads during iteration over interval entries, leading to process termination. This vulnerability requires the malicious message to originate from a device already joined to the network and impacts only devices supporting the Simple Metering cluster. No data leakage back to the sender was observed. The vulnerability is tracked as CWE-125 (Out-of-bounds Read) and has a CVSS 4.0 base score of 7.1, indicating high severity. No official patch or remediation level has been published by Silicon Labs as of the data provided.
Potential Impact
Successful exploitation results in out-of-bounds memory reads causing process termination (denial of service) on affected devices. There is no observed information leakage or remote code execution. The impact is limited to devices supporting the Simple Metering cluster that have joined the network.
Mitigation Recommendations
No official patch or remediation guidance is currently available from Silicon Labs. Users should monitor the vendor advisory for updates. Since the vulnerability requires messages from devices already joined to the network, restricting network access and validating device membership may reduce exposure. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
