# Microsoft Security Advisory CVE-2026-109475 - .NET Denial of Service Vulnerability

Link for people: https://infrastack.ai/live/CVE-2026-109475 (this .md is for agents)

Managed HttpListener in .NET recursively processes an unterminated request line, exhausting the process stack. An attacker who sends such a request can crash the process and take the service offline.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the deployed .NET runtime version against the affected ranges: `8.0.0` to `8.0.33`, `9.0.0` to `9.0.22`, `10.0.0` to `10.0.14`, and `11.0.0-preview.1.26104.118` to `11.0.0-rc.3.26522.148`.
- Check application NuGet references for Microsoft.NETCore.App.Runtime.* packages, since self-contained apps carry their own runtime.
- Affected platforms are Linux and macOS only.

## Fix

- .NET 8: `8.0.34`
- .NET 9: `9.0.23`
- .NET 10: `10.0.15`
- .NET 11: `11.0.0`
- Restart applications, and rebuild and redeploy self-contained apps, since updating the machine-wide runtime does not replace their embedded runtime.

## Advisory FAQ

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

Check the deployed runtime and application package versions against the affected ranges above. Self-contained applications include their own runtime; updating a machine-wide runtime does not replace it.

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

Install the applicable runtime or update each independently referenced package to the fixed version above. Restart applications. Rebuild and redeploy self-contained applications; updating a machine-wide runtime does not replace their embedded runtime. An SDK update alone does not update an application's standalone package references.
