CVE-2026-14035: Google Chrome Information Disclosure Flaw

CVE-2026-14035 Overview

CVE-2026-14035 is an insufficient policy enforcement vulnerability in the Bluetooth component of Google Chrome prior to version 150.0.7871.47. A remote attacker can leverage a crafted HTML page to read potentially sensitive information from Chrome's process memory. Exploitation requires user interaction, such as visiting an attacker-controlled webpage. Chromium's internal severity rating for this issue is Low, while the NVD assessment places it in the medium range due to its network attack vector and information disclosure impact. The flaw is categorized under CWE-284: Improper Access Control and affects Chrome across Windows, macOS, and Linux.

Critical Impact
A remote attacker can extract sensitive data from Chrome process memory through a malicious HTML page that abuses Bluetooth policy enforcement gaps.

Technical Details for CVE-2026-14035

Vulnerability Analysis

The vulnerability resides in the Web Bluetooth implementation within Google Chrome. Chrome exposes Bluetooth device interaction to web pages through the Web Bluetooth API, which is governed by permission and policy checks. Insufficient policy enforcement in this component allows a crafted HTML page to trigger code paths that expose uninitialized or adjacent process memory to the renderer context.

The issue is tracked under CWE-284: Improper Access Control. The Chromium security team classifies the underlying defect as Low severity, but the disclosed data may include tokens, pointers, or fragments of user content resident in Chrome's memory space. The EPSS score of 0.22% reflects a low predicted probability of exploitation in the short term, but the network attack vector broadens the potential attacker population.

Additional technical context is available in the Chromium Issue Tracker Entry.

Root Cause

The root cause is missing or incomplete policy checks in the Bluetooth code path that mediates access between untrusted web content and privileged browser memory. When these checks are bypassed or skipped, Chrome returns responses to the renderer that include memory contents the web page should not be able to observe.

Attack Vector

Exploitation is remote and requires user interaction. The attacker hosts a crafted HTML page that issues Web Bluetooth calls designed to reach the vulnerable policy code path. When a victim visits the page, the renderer receives responses containing sensitive process memory. No authentication is required. See the Google Chrome Update Announcement for release details.

No public proof-of-concept or exploit code is available at the time of publication.

Detection Methods for CVE-2026-14035

Indicators of Compromise

Chrome browser instances running versions prior to 150.0.7871.47 that connect to untrusted external sites
Web Bluetooth API calls from unexpected or newly registered domains in browser telemetry
Renderer processes exhibiting anomalous outbound data volumes after visiting unfamiliar pages

Detection Strategies

Inventory installed Chrome versions across endpoints and flag any build below 150.0.7871.47
Correlate DNS and web proxy logs against threat intelligence feeds to identify visits to suspicious pages that request Bluetooth permissions
Monitor Chrome enterprise reporting for unexpected Web Bluetooth permission prompts or grants

Monitoring Recommendations

Enable Chrome Enterprise reporting to centrally track browser version and extension state
Log and review outbound HTTPS destinations from browser renderer processes for atypical patterns
Alert on execution of unpatched Chrome versions after the patch deadline established by internal policy

How to Mitigate CVE-2026-14035

Immediate Actions Required

Update Google Chrome to version 150.0.7871.47 or later on Windows, macOS, and Linux endpoints
Restart browser processes after update to ensure the patched binary is active
Validate patch deployment through centralized endpoint management or Chrome Enterprise reporting

Patch Information

Google addressed the vulnerability in the Chrome stable channel release documented in the Google Chrome Update Announcement. Administrators should target Chrome 150.0.7871.47 or later.

Workarounds

Disable the Web Bluetooth API via the DefaultWebBluetoothGuardSetting enterprise policy set to 2 (block) until patching is complete
Restrict Bluetooth site permissions to a controlled allowlist using WebBluetoothAllowedForUrls
Instruct users to avoid granting Bluetooth prompts on untrusted sites

bash

# Chrome Enterprise policy example (Linux JSON policy file)
# /etc/opt/chrome/policies/managed/bluetooth_policy.json
{
  "DefaultWebBluetoothGuardSetting": 2,
  "BrowserSignin": 1,
  "ComponentUpdatesEnabled": true
}
