CVE-2026-16424: Google Chrome GPU Use After Free Flaw

CVE-2026-16424 Overview

CVE-2026-16424 is a use-after-free vulnerability [CWE-416] in the GPU component of Google Chrome on Android. The flaw affects versions prior to 150.0.7871.182. A remote attacker who has already compromised the renderer process can leverage a crafted HTML page to potentially escape the Chrome sandbox. Google's Chromium team rated the internal severity as High, while the assigned CVSS 3.1 score places this in the critical range due to the scope change and network attack vector.

Critical Impact
Successful exploitation enables sandbox escape from a compromised renderer, allowing an attacker to break out of Chrome's isolation boundary and access resources beyond the browser process on Android devices.

Affected Products

Google Chrome for Android versions prior to 150.0.7871.182
Chromium-based browsers on Android sharing the vulnerable GPU code path
Android devices running the affected Chrome Stable channel

Technical Details for CVE-2026-16424

Vulnerability Analysis

The vulnerability resides in Chrome's GPU process, which handles hardware-accelerated rendering and compositing. A use-after-free condition occurs when the GPU process continues to reference memory that has already been released. An attacker who first compromises the renderer process through a separate flaw can then trigger this dangling reference through crafted HTML and associated graphics operations. Because the GPU process runs with higher privileges than the sandboxed renderer, gaining control of freed memory in this context provides a path to sandbox escape.

Root Cause

The root cause is improper object lifetime management within the GPU component [CWE-416]. Object destruction is not synchronized with all outstanding references, leaving pointers that reference reclaimed memory. When the attacker reallocates that memory with controlled data, subsequent use of the freed object dereferences attacker-controlled fields.

Attack Vector

Exploitation requires two stages. First, the attacker must compromise Chrome's renderer process, typically through a prior JavaScript or DOM vulnerability delivered via a crafted HTML page. Second, the attacker triggers the GPU use-after-free from within the compromised renderer to escape the sandbox. User interaction is required, since the victim must visit or be redirected to the malicious page. The attack traverses the network and does not require prior authentication to the target.

No public proof-of-concept code has been released. Refer to the Chromium Issue Tracker Entry and the Google Chrome Stable Update for vendor technical details.

Detection Methods for CVE-2026-16424

Indicators of Compromise

Unexpected Chrome GPU process crashes or restarts on Android devices, particularly correlated with visits to untrusted pages
Chrome versions on Android reporting a build number below 150.0.7871.182 in browser telemetry
Child processes spawned by Chrome that deviate from the expected Android process tree

Detection Strategies

Inventory Chrome for Android versions across managed mobile fleets and flag any device running a build older than 150.0.7871.182
Correlate mobile browsing telemetry with crash reports from the Chrome GPU process to identify potential exploitation attempts
Monitor for post-exploitation activity on Android endpoints, including unexpected file writes, network callbacks, or privilege changes originating from the Chrome package

Monitoring Recommendations

Enable enterprise reporting through Chrome Browser Cloud Management or MDM to collect version and crash data from Android endpoints
Track outbound connections from mobile devices to newly registered or low-reputation domains that may host exploit chains
Review web filtering and DNS logs for indicators of drive-by delivery pages that pair a renderer exploit with a GPU sandbox escape

How to Mitigate CVE-2026-16424

Immediate Actions Required

Update Google Chrome on all Android devices to version 150.0.7871.182 or later through the Google Play Store
Enforce minimum Chrome version policies via mobile device management to block outdated installations
Communicate the update requirement to end users and verify compliance across BYOD and corporate-owned Android devices

Patch Information

Google has released the fix in the Chrome Stable channel for Android at version 150.0.7871.182. Details are published in the Google Chrome Stable Update release notes, with the underlying fix tracked in the Chromium Issue Tracker Entry. Apply the update as soon as it is available in the Play Store for your device.

Workarounds

Restrict browsing to trusted sites on unpatched Android devices until the Chrome update can be applied
Use enterprise mobile threat defense controls to block navigation to untrusted or newly registered domains
Where feasible, disable GPU acceleration for high-risk users through managed configuration until patching is complete

bash

# Example: Enforce minimum Chrome version via Android Enterprise managed configuration
# Set the following key in the com.android.chrome managed configuration:
#   BrowserSwitcherEnabled: false
#   ChromeVariations: 0
# Combined with an MDM compliance rule requiring package version >= 150.0.7871.182
adb shell dumpsys package com.android.chrome | grep versionName
