Answer in brief
CVE-2026-47147 records a High severity (CVSS 7.1) vulnerability in OTA server raw parser missing per-field bounds validation in EmberZNet v9.0.2. The current sources do not mark it as known exploited. The current feed maps Silicon Labs/EmberZNet (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
