"The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2026:68335 advisory.

    Red Hat Edge Manager (RHEM) provides simple, scalable, and security-focused
    management of edge devices and applications. It supports image-mode RHEL and
    container workloads that run on Podman/Docker or Kubernetes.

    RHEM is now available as a standalone feature, providing greater flexibility for
    edge deployments. In addition to the standalone version, RHEM continues to be
    offered as a plugin for the following platforms:

    Red Hat Advanced Cluster Management (RHACM): Extends fleet management to edge
    devices.
    Red Hat Ansible Automation Platform (AAP): Integrates edge management with
    Ansible automation.

    This integration enables organizations to optimize the management and
    orchestration of their fleets of edge devices; whether its thousands of
    dispersed retail point-of-sale systems or industrial machinery on remote factory
    floors.

    Value for customers and partners:

    * This solution not only helps customers manage thousands of devices but helps
    scale operations.
    * To manage large-scale deployments, customers need to be able to integrate with
    their existing management systems, support remote configuration and over-the-air
    updates, and collect telemetry data for advanced analytics.
    * Red Hat Edge Manager offers a simple and security-focused lifecycle
    management, from onboarding to decommissioning of edge devices.

    This complete end-to-end solution empowers organizations to gain the most value
    from the fleets of devices that generate data, all from a centralized location.

    Security Fixes:

    * flightctl: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries
    (CVE-2026-27145)
    * flightctl: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal (CVE-2026-33818)
    * flightctl: OpenTelemetry-Go: Denial of Service via oversized baggage headers (CVE-2026-41178)
    * flightctl: Billy: Denial of Service via crafted input due to insufficient validation (CVE-2026-44740)
    * flightctl: Arc: Information disclosure and Denial of Service via unauthenticated debug endpoints
    (CVE-2026-48050)
    * flightctl: golang.org/x/text: Denial of Service via invalid UTF-8 input (CVE-2026-56852)
    * flightctl: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service (CVE-2026-56853)
    * flightctl: Go html/template: Cross-Site Scripting via pathological input (CVE-2026-56858)
    * flightctl: Go: Denial of Service via XML decoding recursion depth issue (CVE-2026-56859)
    * flightctl: golang net/url: Denial of Service from quadratic complexity in path resolution
    (CVE-2026-56860)
    * flightctl: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages (CVE-2026-56862)
    * flightctl: go-git: Arbitrary file read/write via symbolic link resolution (CVE-2026-71556)
