Yes. CVE-2023-21237, Android Pixel Information Disclosure Vulnerability , is being exploited in the wild. CISA added it to its Known Exploited Vulnerabilities catalog on 5 Mar 2024, 251 days after it was published. It affects Android Pixel. If you run it, CISA's required action is: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

What it is

Android Pixel contains a vulnerability in the Framework component, where the UI may be misleading or insufficient, providing a means to hide a foreground service notification. This could enable a local attacker to disclose sensitive information.

What to do

1. Check whether you run it. Look for Pixel in your asset inventory, including appliances and cloud images. Stack check lists every exploited Android CVE at once.
2. Apply the fix. Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
3. If you can't patch today, take the affected service off the internet or restrict who can reach it, and check its logs for signs of compromise since 28 Jun 2023.
4. Get told next time. Email alerts when CISA adds a CVE for Android.
