Attackers can exploit this flaw without credentials to render the device completely unresponsive to remote control or front-panel input, requiring a physical power cycle to restore functionality.","epss":null,"exploits":[{"kind":"exploit","source":"CNA: VulnCheck","url":"https://github.com/yehia-mamdouh/Hisense-Smart-TV-Security-Research"}],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.5,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793991543091,"publishedAt":1793991543091,"references":[{"source":"CNA: VulnCheck","tags":["technical-description","exploit"],"url":"https://github.com/yehia-mamdouh/Hisense-Smart-TV-Security-Research"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/hisense-vidaa-smart-tv-unauthenticated-dos-via-setavtransporturi"}],"remediation":[],"revision":"29803a16bb653150e23682984735e1877b4782ec9a31ab4c448e48998e91ff6f","sources":[{"modifiedAt":1793991543091,"name":"CNA: VulnCheck","retrievedAt":1793992251185,"url":"https://www.cve.org/CVERecord?id=CVE-2026-123997"}],"ssvc":null,"status":"published","title":"Hisense VIDAA Smart TV Unauthenticated DoS via SetAVTransportURI","updatedAt":1793992251185}
