The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - [This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities     correspond to which CVE.] There are two issues related to the mapping of pages belonging to other domains:
    For one, an assertion is wrong there, where the case actually needs handling. A NULL pointer de-reference     could result on a release build. This is CVE-2025-58144. And then the P2M lock isn't held until a page     reference was actually obtained (or the attempt to do so has failed). Otherwise the page can not only     change type, but even ownership in between, thus allowing domain boundaries to be violated. This is     CVE-2025-58145. (CVE-2025-58145)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-873ad6df70 advisory.
