CVE-2026-47147 Details
Description
In EmberZNet v9.0.2 and earlier, malformed OTA requests can drive the OTA server parser into out-of-bounds reads. A limited amount of data from RAM is read back to the requester. The size and location of this data is limited. These requests must come from a device that has already joined the network. Only devices supporting the OTA Server cluster may be impacted.
A vulnerability in the EmberZNet SDK, specifically in versions through 9.0.2, allows for out-of-bounds read errors in the Over-The-Air (OTA) server parser. This issue arises from malformed OTA requests, which can be sent by devices that have already joined the network and support the OTA Server cluster. The vulnerability enables a limited amount of data from RAM to be read and returned to the requester.
Users can update to EmberZNet version 2026.6 to address this vulnerability.
