"The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by a vulnerability as referenced
in the RHSA-2025:3685 advisory.

    Red Hat Edge Manager provides streamlined management of edge devices and
    applications through a declarative approach. By defining the required state of
    your edge devices, which includes your operating system versions, host
    configurations, and application deployments, Red Hat Edge Manager automatically implements and maintains
    these configurations across your entire device fleet.

    You can use Red Hat Edge Manager with Red Hat Advanced Cluster Management to
    manage non-Kubernetes workloads and your operating system configuration on a Red Hat Enterprise Linux
    machine consistently with how you manage it on Red Hat OpenShift Container Platform.

    This advisory contains the RPMs for the Technology Preview version 0.5.1 of Red Hat Edge Manager. See the
    following Release Notes documentation, which will be available shortly for this release, for additional
    details about this release:

    Security fix(es):

    golang.org/x/crypto/ssh: Denial of Service in the Key Exchange of
    golang.org/x/crypto/ssh (CVE-2025-22869)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
