# CVE-2023-21237: Android Pixel Information Disclosure Vulnerability 

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Android Pixel. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-03-05, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-03-26 ; treat that as the outer limit, not the target.
- EPSS 0.3% , percentile 17: FIRST’s model estimates a 0.3% chance of exploitation activity in the next 30 days, higher than 17% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.

## What it is

In applyRemoteView of NotificationContentInflater.java, there is a possible way to hide foreground service notification due to misleading or insufficient UI. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-251586912
