CVE-2020-9057 describes a critical vulnerability in Z-Wave devices utilizing Silicon Labs 100, 200, and 300 series chipsets, including specific Linear products, due to their lack of encryption support. An attacker within radio range can achieve full control, cause denial of service, or replay Z-Wave traffic. This vulnerability carries a CVSS score of 8.8 (HIGH), indicating a low-complexity attack requiring only adjacent network access with high impact on confidentiality, integrity, and availability. While the vulnerability cannot be patched via firmware, upgrading to devices with 500 or 700 series chipsets supporting Security 2 (S2) encryption mitigates the risk. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
