Answer in brief
CVE-2026-4526 records a High severity (CVSS 7.1) vulnerability in Global ZCL command parser missing minimum-length 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 global ZCL messages can trigger out-of-bounds reads in framework parsing logic 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.
