CVE-2026-14062: Google Chrome Information Disclosure Flaw

CVE-2026-14062 Overview

CVE-2026-14062 is an information disclosure vulnerability in the Views component of Google Chrome on ChromeOS. Versions prior to 150.0.7871.47 contain an inappropriate implementation that allows a crafted Chrome Extension to read potentially sensitive data from process memory. An attacker must first convince a user to install a malicious extension. The issue is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor. Google assigned an internal Chromium severity of Low, while the NVD scored the issue 5.9 using the vector CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N.

Critical Impact
A malicious Chrome Extension can read sensitive data from renderer process memory on ChromeOS devices running Chrome versions prior to 150.0.7871.47.

Affected Products

Google Chrome on ChromeOS prior to 150.0.7871.47

Technical Details for CVE-2026-14062

Vulnerability Analysis

The flaw resides in the Views UI framework used by Chrome on ChromeOS. Views manages window, widget, and control rendering across the browser. An inappropriate implementation in this component fails to correctly bound or sanitize data returned to extension-accessible APIs. A crafted Chrome Extension can leverage this behavior to read fragments of process memory that should remain isolated from the extension sandbox. The exposed data may include contents left in reusable buffers, pointers, or user data handled by browser UI code. The issue only affects the ChromeOS build of Chrome, not Windows, macOS, or Linux desktop builds.

Root Cause

The root cause is a logic error in how the Views implementation on ChromeOS handles memory buffers exposed through extension-reachable interfaces. The component returns data without adequately constraining the read boundary or clearing residual bytes. This aligns with CWE-200, where sensitive information from process memory is exposed to a less-privileged actor — in this case, an installed extension.

Attack Vector

Exploitation is network-adjacent but requires user action. The attacker must persuade a target to install a malicious Chrome Extension from the Web Store, a sideload source, or a developer-mode load. Once installed, the extension issues crafted calls that trigger the Views code path and receives memory contents in the response. No additional privileges or user interaction are required after installation. The high attack complexity reflects the need for social engineering and the probabilistic nature of what memory is exposed. See the Chromium Issue Tracker #502448128 and the Google Chrome Stable Update advisory for further technical detail.

Detection Methods for CVE-2026-14062

Indicators of Compromise

Chrome or ChromeOS builds reporting a version earlier than 150.0.7871.47 in chrome://version.
Extensions requesting broad Views or UI-related permissions without a clear functional need.
Unexpected extensions installed outside managed policy, especially from developer mode or sideloaded .crx files.

Detection Strategies

Inventory all installed Chrome Extensions across managed ChromeOS fleets using Google Admin console reporting.
Correlate extension IDs against known-good allowlists and flag unmanaged or recently added entries.
Monitor for extensions that were force-installed or self-installed after the CVE publication date of 2026-06-30.

Monitoring Recommendations

Enable Chrome Enterprise reporting to surface extension installs, permissions, and version telemetry.
Alert on ChromeOS endpoints that fail to update to 150.0.7871.47 or later within the patch window.
Review extension update logs for permission escalations that could indicate a malicious version bump.

How to Mitigate CVE-2026-14062

Immediate Actions Required

Force ChromeOS devices to update to version 150.0.7871.47 or later through the Google Admin console.
Restrict extension installation to an allowlist managed by the ExtensionInstallAllowlist policy.
Remove or disable any unmanaged extensions currently installed on enterprise ChromeOS devices.

Patch Information

Google released the fix in the Stable channel update for ChromeOS. Upgrade to Chrome on ChromeOS 150.0.7871.47 or newer. Refer to the Google Chrome Stable Update advisory for full release notes. The EPSS score of the vulnerability is low, and no public proof-of-concept or in-the-wild exploitation has been reported.

Workarounds

Block extension installs by setting ExtensionInstallBlocklist to * and allowlisting only vetted IDs.
Disable developer mode extension loading through DeveloperToolsAvailability policy on managed devices.
Train users to install extensions only from verified publishers and to review requested permissions.

bash

# ChromeOS enterprise policy example: restrict extensions to an allowlist
# Apply via Google Admin console > Devices > Chrome > Users & browsers > Apps and extensions
ExtensionInstallBlocklist = ["*"]
ExtensionInstallAllowlist = [
  "aapocclcgogkmnckokdopfmhonfmgoek",  # example: approved extension ID
  "felcaaldnbdncclmgdcncolpebgiejap"   # example: approved extension ID
]
DeveloperToolsAvailability = 2  # Disallow developer tools
