CVE-2026-14401 Overview
CVE-2026-14401 is a high-severity input validation vulnerability in the ANGLE (Almost Native Graphics Layer Engine) component of Google Chrome on Android. The flaw affects Chrome versions prior to 150.0.7871.46. A remote attacker who has already compromised the renderer process can leverage a crafted HTML page to potentially escape the Chrome sandbox. Successful exploitation moves an attacker from the constrained renderer context into a higher-privileged process, expanding access on the Android device. Google classified the Chromium security severity as High.
Critical Impact
Attackers who compromise the renderer process can chain this flaw to escape the Chrome sandbox on Android, breaking a core browser security boundary.
Affected Products
- Google Chrome for Android prior to 150.0.7871.46
- ANGLE graphics translation layer as shipped in Chromium
- Chromium-based mobile builds inheriting the vulnerable ANGLE code

Technical Details for CVE-2026-14401
Vulnerability Analysis
The vulnerability resides in ANGLE, the graphics abstraction layer that translates OpenGL ES API calls into the platform's native graphics APIs. ANGLE processes graphics commands passed from the renderer process, which handles untrusted web content. Insufficient validation of untrusted input allows a compromised renderer to submit crafted graphics data that ANGLE mishandles. Because ANGLE code executes in a context with broader privileges than the sandboxed renderer, mishandled input can be leveraged to cross the sandbox boundary. The issue is categorized under [CWE-20] Improper Input Validation.
Root Cause
ANGLE fails to fully validate data supplied by the renderer process before acting on it. The trust model assumes the renderer is untrusted, so ANGLE must treat all inputs as hostile. Missing or incomplete input checks in the affected code paths allow malformed graphics commands to reach lower-level handling routines.
Attack Vector
Exploitation requires two stages. First, the attacker must compromise the renderer process, typically through a separate memory corruption or logic bug triggered by a crafted HTML page. Second, the attacker uses the controlled renderer to send malicious input to ANGLE, triggering the sandbox escape. User interaction, such as visiting an attacker-controlled page, is required. The attack complexity is elevated because chaining a renderer compromise with the ANGLE flaw is non-trivial.
No public proof-of-concept exploit is currently available for CVE-2026-14401. See the Chromium Issue Tracker Entry and the Google Chrome Update Blog for vendor details.
Detection Methods for CVE-2026-14401
Indicators of Compromise
- Chrome for Android processes crashing with GPU or ANGLE-related stack frames after visiting untrusted pages
- Unexpected child process creation or privilege transitions originating from Chrome on Android endpoints
- Outbound connections from mobile devices to newly registered domains hosting exploit-like HTML content
Detection Strategies
- Inventory Chrome for Android installations and flag any version below 150.0.7871.46 as vulnerable
- Monitor mobile threat telemetry for anomalous Chrome renderer or GPU process behavior
- Correlate browser crash reports with visits to untrusted domains to surface potential exploitation attempts
Monitoring Recommendations
- Ingest Android application version data into your SIEM and alert on out-of-date Chrome builds
- Track Chromium security advisories and map them to installed browser versions across managed devices
- Enable crash and telemetry reporting in enterprise mobility management to surface exploitation indicators
How to Mitigate CVE-2026-14401
Immediate Actions Required
- Update Google Chrome on Android to version 150.0.7871.46 or later on all managed devices
- Force browser updates through mobile device management for corporate-owned Android endpoints
- Advise users to avoid untrusted links and enable automatic updates in the Google Play Store
Patch Information
Google released the fix in Chrome for Android 150.0.7871.46. Refer to the Google Chrome Update Blog for the stable channel announcement and the Chromium Issue Tracker Entry for the underlying bug reference.
Workarounds
- No official workaround exists; patching is the only supported remediation
- Restrict browsing on unpatched devices to trusted, allowlisted sites until updates are applied
- Consider temporarily using an alternate, patched browser on Android if update deployment is delayed
# Verify installed Chrome version on Android via adb
