When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool.

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:36796 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.

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

The version of Golang running on the remote host is 1.25.x prior to 1.25.9, or 1.26.x prior to 1.26.2. It is, therefore, affected by multiple vulnerabilities, including:

  - Arithmetic over induction variables in loops were not correctly checked for underflow or overflow. As a result, the     compiler would allow for invalid indexing to occur at runtime, potentially leading to memory corruption.
    (CVE-2026-27143)

  - SWIG file names containing 'cgo' and well-crafted payloads could lead to code smuggling and arbitrary code     execution at build time due to trust layer bypass. (CVE-2026-27140)

  - The compiler is meant to unwrap pointers which are the operands of a memory move; a no-op interface conversion     prevented the compiler from making the correct determination about non-overlapping moves, potentially leading to     memory corruption at runtime. (CVE-2026-27144)

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

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

  - When verifying a certificate chain containing excluded DNS constraints, these constraints are not     correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects     validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots     CertPool, or in the system certificate pool. (CVE-2026-33810)

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

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - When verifying a certificate chain containing excluded DNS constraints, these constraints are not
    correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects
    validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots
    CertPool, or in the system certificate pool. (CVE-2026-33810)
