CVE-2026-47149: CWE-125: Out-of-bounds Read in Silicon Labs EmberZNet
In EmberZNet v9.0.2 and earlier, malformed or out-of-range Door Lock user identifiers can trigger out-of-bounds table reads 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 Door Lock cluster may be impacted.
AI Analysis
Technical Summary
This vulnerability in EmberZNet (<=9.0.2) allows an attacker with network access and privileges to send malformed Door Lock user identifiers that cause out-of-bounds reads in a table, leading to process termination (denial of service). The flaw is categorized as CWE-125 (Out-of-bounds Read). Exploitation requires the attacker device to be part of the network and support the Door Lock cluster. There is no evidence of information leakage or further compromise beyond process termination.
Potential Impact
Successful exploitation results in denial of service by terminating the affected process on devices supporting the Door Lock cluster. No data leakage or privilege escalation has been observed. The vulnerability requires the attacker to have joined the network, limiting exposure to internal or compromised devices.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to trusted devices only, especially those supporting the Door Lock cluster, to reduce risk. Monitor for unusual process terminations on affected devices.
