The Microsoft .NET Framework installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - Allocation of resources without limits or throttling in .NET allows an unauthorized attacker to deny     service over a network. (CVE-2026-47302)

  - Stack-based buffer overflow in .NET Framework allows an unauthorized attacker to deny service over a     network. (CVE-2026-50527)

  - Protection mechanism failure in .NET Framework allows an unauthorized attacker to execute code locally.
    (CVE-2026-50646)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:58568 advisory.

    .NET is a fast, lightweight and modular platform for creating cross platform applications that work on     Linux, macOS and Windows.  It particularly focuses on creating console applications, web applications and     micro-services.  .NET contains a runtime conforming to .NET Standards a set of framework libraries, an SDK     containing compilers and a 'dotnet' application to drive everything.
