CVE-2026-113032 Overview
CVE-2026-113032 is a memory corruption vulnerability in the Omnibox component of Google Chrome on Android. The flaw affects Chrome versions prior to 156.0.8078.47. A remote attacker can exploit the issue by serving a crafted HTML page, triggering arbitrary code execution inside the Chrome sandbox. Google tracks the issue under Chromium severity Medium, while NVD scores it 8.8 (High) under CVSS 3.1. The vulnerability maps to CWE-119, improper restriction of operations within memory buffer bounds. Exploitation requires user interaction, specifically visiting a malicious page in a vulnerable Chrome build on Android.
Critical Impact
A remote attacker can execute arbitrary code within the Chrome sandbox on Android devices by convincing a user to visit a crafted web page.
Affected Products
- Google Chrome for Android versions prior to 156.0.8078.47
- Google Android running vulnerable Chrome builds
- Chromium-derived browsers on Android that embed the affected Omnibox code

Technical Details for CVE-2026-113032
Vulnerability Analysis
The Omnibox is the combined address and search bar in Chrome. It parses user input, URL suggestions, and autocomplete data from multiple sources. CVE-2026-113032 is a memory corruption condition in that component, classified under [CWE-119]. An attacker-controlled HTML page can influence Omnibox state or data handling in a way that corrupts memory. The condition allows arbitrary code execution within the renderer sandbox. Code running inside the sandbox is isolated, but it can still be chained with a sandbox escape to achieve full device compromise on Android.
Root Cause
The root cause is improper restriction of operations within the bounds of a memory buffer in Omnibox code paths. Chromium's advisory and the Chromium issue tracker entry #541604102 describe the fix at a high level without releasing low-level technical details before broad patch adoption. Memory corruption in Omnibox typically involves mishandled string, URL, or suggestion buffers during parsing or UI update operations.
Attack Vector
Exploitation is network-based and requires user interaction. The victim must load a crafted HTML page in a vulnerable Chrome for Android build. No authentication is required. Delivery vectors include phishing links, malicious advertisements, compromised sites, and in-app browser previews that embed Chrome's rendering stack. Successful exploitation yields code execution inside the renderer sandbox, which attackers commonly pair with a secondary sandbox escape for privilege gain. No public proof-of-concept or exploit code is listed, and the issue is not currently on the CISA Known Exploited Vulnerabilities catalog.
No verified public exploit code is available for this issue. See the Chromium Issue Tracker #541604102 and the Google Chrome Desktop Update for vendor details.

Stop Exploit AttemptsDetection Methods for CVE-2026-113032
Indicators of Compromise
- Android devices running Chrome versions earlier than 156.0.8078.47 that have browsed untrusted sites.
- Unexpected Chrome renderer process crashes or tombstone files on Android around the time of visiting unknown URLs.
- Outbound network connections initiated by Chrome child processes to previously unseen domains following a crash event.
Detection Strategies
- Inventory installed Chrome versions on managed Android fleets through mobile device management (MDM) and flag any build below 156.0.8078.47.
- Correlate browser crash telemetry with recent URL navigation history to surface pages that may be triggering memory corruption.
- Monitor threat intelligence feeds for proof-of-concept release or in-the-wild exploitation tied to Chromium issue #541604102.
Monitoring Recommendations
- Alert on Android endpoints that remain on outdated Chrome versions beyond a defined patch SLA.
- Watch for anomalous child process behavior from the Chrome package, including unexpected file writes or network sockets.
- Capture and review DNS and HTTP telemetry from mobile endpoints for connections to known malicious or newly registered domains.
How to Mitigate CVE-2026-113032
Immediate Actions Required
- Update Google Chrome for Android to version 156.0.8078.47 or later through the Google Play Store.
- Push the update to managed Android devices using MDM policies that enforce minimum Chrome versions.
- Advise users to avoid clicking untrusted links until the update is confirmed installed.
Patch Information
Google released the fix in Chrome 156.0.8078.47 for Android. Details are referenced in the Google Chrome Release Notes and tracked in Chromium Issue #541604102. Users should verify installation under Chrome settings, in the About Chrome section, after the Play Store update completes.
Workarounds
- Use an alternative, fully patched Chromium-based or Gecko-based browser on Android until Chrome is updated.
- Enable Google Play Protect and automatic app updates to shorten exposure windows for future Chrome vulnerabilities.
- Apply web filtering at the network or DNS layer to block known malicious domains that could host exploit payloads.
