CVE-2026-11692: Google Chrome Use-After-Free Vulnerability

CVE-2026-11692 Overview

CVE-2026-11692 is a use-after-free vulnerability [CWE-416] in the Read Anything component of Google Chrome prior to version 149.0.7827.103. A remote attacker who has already compromised the renderer process can leverage a crafted HTML page to potentially escape the Chrome sandbox. Chromium's security team classifies the issue at High severity. The flaw affects Chrome on Windows, macOS, and Linux desktop builds. Because the vulnerability targets the browser sandbox boundary, successful exploitation grants the attacker access to a higher privilege context than the constrained renderer.

Critical Impact
Successful exploitation enables a sandbox escape from a compromised renderer, expanding attacker capabilities from web content execution to broader access on the host process boundary.

Affected Products

Google Chrome versions prior to 149.0.7827.103
Chrome desktop on Microsoft Windows
Chrome desktop on Apple macOS and Linux

Technical Details for CVE-2026-11692

Vulnerability Analysis

The vulnerability resides in Read Anything, a Chrome feature that produces a simplified reading view of web page content. A use-after-free condition occurs when the component dereferences memory after the associated object has been released. An attacker who already controls the renderer process can manipulate object lifetimes through a crafted HTML page to reclaim freed memory and steer execution. The bug becomes a sandbox-escape primitive because Read Anything interacts with privileged browser-side code paths beyond the renderer.

The attack chain assumes a prior renderer compromise, which raises exploitation complexity. The user must also interact with the malicious page for the attack to succeed. Once chained, the impact spans confidentiality, integrity, and availability of the browser process.

Root Cause

The root cause is improper lifetime management of an object accessed by the Read Anything feature. After the object is freed, a dangling reference remains reachable, and a subsequent access reads or writes attacker-controlled memory. This is a classic CWE-416 condition. Details are tracked in the Chromium Issue Tracker Entry.

Attack Vector

Exploitation requires a network-delivered crafted HTML page and user interaction with that page. The attacker must first achieve renderer-process compromise, typically through a separate renderer exploit. The use-after-free in Read Anything is then triggered to cross the sandbox boundary. No prose-only walkthrough of exploit code is published. Refer to the Google Chrome Desktop Update advisory for vendor-supplied context.

Detection Methods for CVE-2026-11692

Indicators of Compromise

Chrome renderer or utility processes spawning unexpected child processes after a user visits an untrusted page.
Crash reports or chrome.exe minidumps referencing the Read Anything component or accessibility-related modules.
Outbound connections from browser-spawned processes to attacker-controlled infrastructure shortly after page navigation.

Detection Strategies

Inventory installed Chrome versions across the fleet and flag any host running a build earlier than 149.0.7827.103.
Hunt for anomalous browser process trees where Chrome subprocesses execute payloads outside expected directories.
Correlate browser crash telemetry with web proxy logs to identify users who loaded suspicious HTML prior to the crash.

Monitoring Recommendations

Forward Chrome version inventory and process-tree telemetry into a SIEM for continuous coverage checks.
Monitor endpoint EDR alerts tagged to browser sandbox escape behaviors and unusual cross-process memory access.
Track navigation events to newly registered or low-reputation domains delivering scripted HTML content.

How to Mitigate CVE-2026-11692

Immediate Actions Required

Update Google Chrome to version 149.0.7827.103 or later on Windows, macOS, and Linux endpoints.
Enforce automatic Chrome updates through enterprise policy to close the patch gap quickly.
Restart Chrome on all managed devices after the update is staged to apply the fix.

Patch Information

Google released the fix in the Chrome Stable channel as documented in the Google Chrome Desktop Update. Administrators should validate that endpoints report a Chrome version of 149.0.7827.103 or higher. Chromium tracks the underlying defect in the Chromium Issue Tracker Entry.

Workarounds

Restrict browsing to trusted sites through web filtering until patching completes.
Disable or restrict the Read Anything feature via enterprise policy where supported.
Apply site isolation and strict process limits to reduce the value of a renderer compromise.
