An attacker with adjacent short-range access to an affected product, in situations where the product’s radio is turned on, can inject, replay, modify, and/or intercept data within the telemetry communication. This communication protocol provides the ability to read and write memory values to affected implanted cardiac devices; therefore, an attacker could exploit this communication protocol to change memory in the implanted cardiac device.","published":"2019-03-25T22:29:01.000Z","lastModified":"2026-06-17T02:39:13.000Z","status":"Modified","sourceIdentifier":"ics-cert@hq.dhs.gov","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-284","CWE-306","CWE-862"],"affected":["medtronic/mycarelink monitor firmware","medtronic/carelink monitor firmware","medtronic/carelink 2090 firmware","medtronic/amplia crt-d firmware","medtronic/claria crt-d firmware","medtronic/compia crt-d firmware","medtronic/concerto crt-d firmware","medtronic/concerto ii crt-d firmware","medtronic/consulta crt-d firmware","medtronic/evera icd firmware","medtronic/maximo ii crt-d and lcd firmware","medtronic/mirro icd firmware","medtronic/nayamed nd icd firmware","medtronic/primo icd firmware","medtronic/protecta icd and crt-d firmware","medtronic/secura icd firmware","medtronic/virtuoso icd firmware","medtronic/virtuoso ii icd firmware","medtronic/visia af icd firmware","medtronic/viva crt-d firmware"],"epss":{"score":0.00895,"percentile":0.59277,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.90%).
