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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-306","CWE-862","CWE-284"],"references":["http://www.securityfocus.com/bid/107544","https://ics-cert.us-cert.gov/advisories/ICSMA-19-080-01","http://www.securityfocus.com/bid/107544","https://ics-cert.us-cert.gov/advisories/ICSMA-19-080-01"],"products":["medtronic:amplia_crt-d_firmware","medtronic:carelink_2090_firmware","medtronic:carelink_monitor_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:mycarelink_monitor_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"],"source":"nvd","synced_at":"2026-10-19T20:55:22.313337056+00:00"},"epss":{"cve":"CVE-2019-6538","score":0.00895,"percentile":0.59549,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
