CVE-2025-8010

8.8 HIGH

📋 TL;DR

A type confusion vulnerability in Chrome's V8 JavaScript engine allows attackers to trigger heap corruption by tricking the engine into treating one data type as another. This affects all users running vulnerable versions of Google Chrome. Successful exploitation could lead to arbitrary code execution.

💻 Affected Systems

Products:
  • Google Chrome
  • Chromium-based browsers
Versions: All versions prior to 138.0.7204.168
Operating Systems: Windows, macOS, Linux, Android, iOS
Default Config Vulnerable: ⚠️ Yes
Notes: All default Chrome configurations are vulnerable. Extensions or security settings do not mitigate this vulnerability.

📦 What is this software?

Chrome by Google

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution with the same privileges as the Chrome process, potentially leading to full system compromise if combined with privilege escalation.

🟠

Likely Case

Browser crash (denial of service) or limited memory corruption leading to information disclosure.

🟢

If Mitigated

Browser sandboxing prevents full system compromise, limiting impact to browser process isolation boundaries.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

Exploitation requires user interaction (visiting malicious website) but no authentication. Type confusion vulnerabilities in V8 have historically been exploited in the wild.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 138.0.7204.168

Vendor Advisory: https://chromereleases.googleblog.com/2025/07/stable-channel-update-for-desktop_22.html

Restart Required: Yes

Instructions:

1. Open Chrome. 2. Click the three-dot menu. 3. Go to Help > About Google Chrome. 4. Chrome will automatically check for and install updates. 5. Click 'Relaunch' to restart Chrome with the patched version.

🔧 Temporary Workarounds

Disable JavaScript

all

Prevents exploitation by disabling JavaScript execution, but breaks most website functionality.

Use Site Isolation

all

Ensure Chrome's Site Isolation feature is enabled (default) to limit impact scope.

🧯 If You Can't Patch

  • Restrict access to untrusted websites using web filtering or proxy controls.
  • Implement application whitelisting to prevent execution of malicious payloads that might escape the browser sandbox.

🔍 How to Verify

Check if Vulnerable:

Check Chrome version in Settings > About Chrome. If version is below 138.0.7204.168, the system is vulnerable.

Check Version:

On Windows: "C:\Program Files\Google\Chrome\Application\chrome.exe" --version
On macOS: /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version
On Linux: google-chrome --version

Verify Fix Applied:

Confirm Chrome version is 138.0.7204.168 or higher in Settings > About Chrome.

📡 Detection & Monitoring

Log Indicators:

  • Chrome crash reports with V8-related stack traces
  • Unexpected Chrome process termination events

Network Indicators:

  • Requests to known malicious domains hosting exploit code
  • Unusual outbound connections from Chrome processes

SIEM Query:

source="chrome_crash_reports" AND (message="V8" OR message="type confusion" OR message="heap corruption")
