Chrome for Android GPU Sandbox Escape

CVE advisorySeverity: CRITICAL (CVSS 9.6)

CVE-2026-11119

This vulnerability requires a user to navigate to a crafted HTML page within a specific browser environment to trigger the issue. Because it is a client-side browser vulnerability that relies on user interaction and renderer process compromise, it lacks the characteristics of a public-facing service, gateway, or internet-exposed appliance.

Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.

Horizon Alert

Summary of the vulnerability and why it matters

A security vulnerability exists in Google Chrome on Android that could allow a remote attacker to escape the browser's security sandbox. This type of vulnerability means that if an attacker can trick a user into visiting a malicious webpage, they may be able to gain greater access to the device than they should. The main concern is confirming relevance and exposure.

  • An attacker could bypass security using a malicious webpage.
  • It could allow wider system access if exploited.
  • Confirm relevance and exposure for your Android Chrome users.

Attack Path

How an attacker could exploit the issue

A remote attacker who has already compromised the renderer process could lure a user into visiting a specially crafted HTML page. This interaction allows the attacker to potentially escape the sandbox environment, leading to broader system compromise.

  • Entry condition: Compromised renderer process.
  • Trigger point: Visiting a crafted HTML page.
  • Resulting risk: Sandbox escape and potential system compromise.

Live Threat

Current exploitation, exposure, and threat context

A sandbox escape in Chrome on Android could allow a compromised renderer process to affect system integrity when a user visits a malicious HTML page.

  • System integrity and user data.
  • Visiting a malicious HTML page.
  • Potential unauthorized system actions.

Operational Fix

Recommended remediation, mitigation, and detection steps

In real-world scenarios, the Google Chrome on Android application owners and the Android platform team are likely responsible for addressing this vulnerability. The first practical step is to identify all Android devices running Chrome, determine their exposure, and confirm ownership before planning remediation.

  • Confirm Chrome on Android asset ownership.
  • Verify user interaction and exposure paths.
  • Coordinate vendor updates with maintenance windows.

Frequently asked questions

What is Google Chrome on Android?

Google Chrome on Android is a web browser built on the Chromium engine. It manages how your device renders websites, executes JavaScript, and interacts with hardware like the GPU to display graphics. By isolating these activities within a security sandbox, the browser prevents individual websites from accessing other apps or sensitive system data.

What does CWE-20 mean for CVE-2026-11119?

This CVE involves CWE-20, which is Improper Input Validation. In this context, it means the browser's GPU component fails to properly check or sanitize the data it receives from a webpage. Because of this flaw, the browser processes malicious instructions incorrectly, which can lead to a sandbox escape and allow an attacker to bypass the security boundaries normally protecting your device.

How is this vulnerability triggered?

An attacker must first compromise the browser's renderer process and then lure a user to a specially crafted HTML page. Simply having the browser installed or running in the background does not trigger the bug. If a user does not interact with the specific malicious content designed to exploit this GPU implementation flaw, the vulnerability remains inactive.

Do I need to worry about this if my devices are internal?

Halo Surface Signal indicates this is a client-side browser issue rather than a public-facing service or gateway vulnerability. Because it relies on a user visiting a specific malicious webpage, the risk is not tied to whether the device is on an internal network or exposed to the internet. The primary factor is the user's web browsing activity on an outdated browser version.

When should I take action on CVE-2026-11119?

You should begin by identifying which Android devices in your environment are running Chrome versions older than 149.0.7827.53. Once you have identified these assets, coordinate with your teams to apply the official browser updates provided by Google. Verifying your device inventory is the recommended first step before scheduling the necessary software updates.
