"According to the versions of the linux-firmware packages installed, the EulerOS installation on the remote host is
affected by the following vulnerabilities :

  - Improper access control for some Intel(R) PROSet/Wireless WiFi and Killer(TM) WiFi software may allow a
    privileged user to potentially enable escalation of privilege via local access. (CVE-2022-27635,
    CVE-2022-40964)

  - Improper input validation in some Intel(R) PROSet/Wireless WiFi and Killer(TM) WiFi software may allow an
    unauthenticated user to potentially enable denial of service via adjacent access. (CVE-2022-36351)

  - Improper input validation in some Intel(R) PROSet/Wireless WiFi and Killer(TM) WiFi software may allow an
    authenticated user to potentially enable escalation of privilege via local access. (CVE-2022-38076)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
