### Advisory FAQ

#### <a name="how-affected"></a>How do I know if I am affected?

If you have a runtime or SDK with a version listed, or an affected package listed in [affected software](#affected-software), you're exposed to the vulnerability.

#### <a name="how-fix"></a>How do I fix the issue?

-   To fix the issue please install the latest version of .NET 6.0 or .NET 7.0. If you have installed one or more .NET SDKs through Visual Studio, Visual Studio will prompt you to update Visual Studio, which will also update your .NET SDKs.
-   If you are using one of the affected packages, please update to the patched version listed above.
-   If you have .NET 6.0 or greater installed, you can list the versions you have installed by running the `dotnet --info` command. You will see output like the following;

To install additional .NET Core runtimes or SDKs:
  https://aka.ms/dotnet-download
```

-   If you're using .NET 7.0, you should download and install Runtime 7.0.11 or SDK 7.0.111 (for Visual Studio 2022 v17.4) from [https://dotnet.microsoft.com/download/dotnet-core/7.0](https://dotnet.microsoft.com/download/dotnet-core/7.0).
-   If you're using .NET 6.0, you should download and install Runtime 6.0.22 or SDK 6.0.317 (for Visual Studio 2022 v17.2) from [https://dotnet.microsoft.com/download/dotnet-core/6.0](https://dotnet.microsoft.com/download/dotnet-core/6.0).

.NET 6.0 and and .NET 7.0 updates are also available from Microsoft Update. To access this either type "Check for updates" in your Windows search, or open Settings, choose Update & Security and then click Check for Updates.

Once you have installed the updated runtime or SDK, restart your apps for the update to take effect.

Additionally, if you've deployed [self-contained applications](https://docs.microsoft.com/dotnet/core/deploying/#self-contained-deployments-scd) targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed.

## Detection & mitigation playbook

Open-source dependency

1.  ### Detect
    
    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Microsoft.NETCore.App.Runtime.win-arm64, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
    
2.  ### Fix
    
    Update Microsoft.NETCore.App.Runtime.win-arm64 to 7.0.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-36792 is resolved across your whole dependency graph.
    
3.  ### Workarounds
    
    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
    

## Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
