Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-8cffa03dad advisory.

 The 7.0.4 stable kernel rebase contains additional hardware support, new features, and a number of important fixes across the tree. It also contains a fix for the dirtyfrag vulnerability. This covers CVE-2026-43284 and CVE-2026-43500. For users who experience a problem with the 7.0.4 rebase, a build of 6.19.14 with just the dirtyfrag fixes should be available in koji shortly.

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

Solution

Update the affected kernel package.
