A limited number of values can be written using this vulnerability, so no route to remote code execution was observed. These messages must come from a device that has already joined the network. Only devices supporting the Group Cluster are impacted.","categories":["Unclassified"],"product":"EmberZNet","vendor":"Silicon Labs","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-85080","source_modified_at":"2026-10-23T10:56:10.233Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"EmberZNet","vendor":"Silicon Labs","versions":[{"status":"affected","version":"0","lessThanOrEqual":"9.1.1","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00354,"percentile":0.27896,"score_date":"2026-10-23"},"published_at":"2026-10-22T13:42:26.160Z","modified_at":"2026-10-23T10:56:10.233Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-85080","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T10:56:10.233Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-85080","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/SiliconLabsSoftware/docs-security-advisories/blob/main/Advisories/500-599/A-00000590.md","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-23T10:49:22.640632Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T10:56:10.233Z","content_hash":"da2616a048a439fb2a82c338001fe5d5cad28f264c3b454706015ad5c56b8261"}}
