The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-defb0a89ff advisory.

  • Improper access control for some Intelยฎ PROSet/Wireless WiFi and Killerโ„ข WiFi software may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2022-27635, CVE-2022-40964)

  • Protection mechanism failure for some Intelยฎ PROSet/Wireless WiFi software may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2022-46329)

  • Improper input validation in some Intelยฎ PROSet/Wireless WiFi and Killerโ„ข WiFi software may allow an unauthenticated user to potentially enable denial of service via adjacent access. (CVE-2022-36351)

  • Improper input validation in some Intelยฎ PROSet/Wireless WiFi and Killerโ„ข WiFi software may allow an authenticated user to potentially enable escalation of privilege via local access. (CVE-2022-38076)

Note that Nessus has not tested for these issues but has instead relied only on the applicationโ€™s self-reported version number.
