What the Cyber Resilience Act (CRA) means for Android™ development

The CRA starts now: 24 hours to respond

Picture this: a critical Android vulnerability is reportedly being exploited. Based on initial analysis, the compromised component is part of your software stack.

Your product runs Android, but probably not exactly the Android described in the Common Vulnerabilities and Exposures (CVE) description. You may have your own system image, configuration, kernel, or product-specific components, with several versions already in development or in the field.

Are you affected?

And how quickly can you find out?

From 11 September 2026, that question becomes more urgent. Under the CRA, manufacturers of products with digital elements within scope may need to issue an early warning within 24 hours of becoming aware of an actively exploited vulnerability, followed by a more detailed notification within 72 hours. And this isn’t only about new products: the reporting obligations also apply to products already available on the EU market.

That doesn’t mean fixing every vulnerability in 24 hours, but it does mean the clock can start before engineering teams have all the answers.

The 24-hour engineering problem

In 2025, we argued that organizations shouldn’t wait until the CRA fully applies in 2027. Before then, it’s critical that they establish processes around secure development, vulnerability handling, traceability, and documentation. As you read this, we have now reached one of the first operational trials for said processes. 

Now, before you can meaningfully respond to a vulnerability, you must first understand how it affects your product. With Android, that can become complicated quickly.

An Android vulnerability might affect the framework, a privileged system service, the kernel, or another component integrated into an Android Open Source Project (AOSP) or Android Automotive Operating System (AAOS) build. Your product may then add a specific Android release and patch level, a custom kernel, modified framework components, or vendor-specific software. One security advisory can therefore trigger a much broader investigation.

Which versions are affected? Is the vulnerable component present and reachable in our configuration? Can we reproduce the issue? Does the mitigation work? Does the patched image introduce regressions?

Those aren’t compliance questions: they’re engineering questions.

Reproducing Android when the clock is running

The limitations of Android development tied too closely to physical devices can slow teams down during normal development, which you can read more about on our blog. However, during a security investigation, that dependency can become much more significant.

Imagine that you discover a vulnerability may affect three versions of your Android product. You need the corresponding devices, the correct images, and the right configurations. Then you need to reproduce the issue, test a mitigation, and repeat everything with the patched build. And, as every developer team knows, you can be sure that the hardware benches you could use to do that are either unavailable, under maintenance, or misconfigured.

Or you can treat those Android environments as software; this is where Anbox Cloud fits.

With Anbox Cloud, teams can create and manage Android environments automatically from known images. Those environments can be replicated on demand, run simultaneously, and be integrated into existing testing and Continuous Integration and Continuous Delivery/Deployment (CI/CD) workflows.

This means that a vulnerability investigation can become a repeatable process: a CVE is identified, and so are the affected configurations; then said configurations can be reproduced for investigation, patching, and validation. Instead of preparing several physical devices sequentially, teams can launch representative environments for different Android versions or product configurations, run the same tests against them, and compare the results. Once a patched image is available, they can repeat the process.

Anbox Cloud also supports two complementary execution models. Containerized Android provides fast startup and high density, making it well suited to application-level validation and parallel testing. Learn how in our documentation.

When the investigation concerns the Android system itself, Anbox Cloud can also run complete Android environments in virtual machines. As we’ve announced recently, this includes Cuttlefish-based and customized AOSP images with their own kernel.

Sometimes you need to know whether your application still works after applying an Android security update. Sometimes the vulnerable component is Android itself. Anbox Cloud gives teams a way to test both within the same infrastructure.

What if vulnerability response looked like CI?

This is perhaps the more interesting opportunity. Software teams already automate what happens after a code change: build the software, provision the environment, execute the tests, and record the results. Vulnerability validation can follow the same principle.

Once a potentially affected Android image has been identified, Anbox Cloud’s APIs can make the environment another part of that pipeline. The team receives a security advisory, launches the affected image, confirms the issue, patches said issue, validates the fix, and provides evidence of a working patch. The workflow can run across multiple Android versions or configurations in parallel. Environments can be recreated later, and the same tests can be executed consistently rather than depending on the state and availability of a particular physical device or hardware bench.

At that point, the usefulness of virtual Android extends beyond reducing hardware dependency; it offers reproducible security infrastructure.

Anbox Cloud doesn’t detect vulnerabilities, decide whether they are reportable under the CRA, or make a product CRA-compliant. Manufacturers remain responsible for vulnerability assessment, remediation, and reporting. Anbox Cloud sits in the engineering work in between: helping teams reproduce what they run, understand what is affected, and validate what they are going to do about it.

How much time will it take you to know whether you are affected?

The CRA’s broader requirements still largely apply from December 2027. But from the 11th of September 2026, vulnerability and incident reporting start becoming an operational reality. For teams building products on Android, that makes the engineering infrastructure behind vulnerability management increasingly important.

The first question after an Android security advisory will still be, “Are we affected?” But the more important operational question may be, “How long will it take us to know?” When the regulatory clock is already running, the ability to reproduce the right Android environment, investigate it, and validate a fix can make a real difference.

24 hours can pass very quickly when you’re still looking for the right device.
