# Cortex XDR supported Kernel Module versions by distribution

On Linux endpoints, to perform malware analysis of Executable and Linkable Format (ELF) files and collect data for endpoint detection and response (EDR) and behavioral threat analysis, the Cortex XDR agent requires a Linux Kernel module.

{% hint style="warning" %}

### Caution

To deploy on a supported Kernel version, you must ensure it is possible to load third party Kernel modules. To do so, you can either:

* Disable UEFI SecureBoot.
* If UEFI SecureBoot is enabled, you must load the Cortex XDR certificate.

To load the certificate, follow the instructions detailed in Cortex XDR Agent Administrator Guide → Cortex XDR Agent for Linux → Install the Cortex XDR Agent for Linux → **Load SecureBoot Certificates**.
{% endhint %}

Changes to the Kernel module versions are distributed with content updates. For earlier Cortex XDR agent releases, changes to the kernel module versions are distributed with the agent releases.

#### Latest Kernel Module versions supported

See the [latest Kernel Module versions](/linux-kernel-versions/readme.md) that are supported.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xdr-agent/9.3/cortex-xdr-agent-for-linux/cortex-xdr-supported-kernel-module-versions-by-distribution.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
