Exploitation of the Wi-Fi device can lead to exploitation of the host application processor in some cases, but this depends on several factors including host OS hardening and the availability of DMA.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-787"],"references":["http://www.securityfocus.com/bid/106865","https://2018.zeronights.ru/wp-content/uploads/materials/19-Researching-Marvell-Avastar-Wi-Fi.pdf","https://embedi.org/blog/remotely-compromise-devices-by-using-bugs-in-marvell-avastar-wi-fi-from-zero-knowledge-to-zero-click-rce/","https://www.kb.cert.org/vuls/id/730261/","https://www.scribd.com/document/398350818/WiFi-CVE-2019-6496-Marvell-s-Statement"],"products":["marvell:88w8787_firmware","marvell:88w8797_firmware","marvell:88w8801_firmware","marvell:88w8897_firmware","marvell:88w8997_firmware"],"source":"nvd","synced_at":"2026-10-19T20:54:46.948512734+00:00"},"epss":{"cve":"CVE-2019-6496","score":0.06617,"percentile":0.93857,"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).
