⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to full system compromise, data theft, or installation of persistent malware.

🟠

Likely Case

Browser crash (denial of service) or limited memory corruption that could be leveraged for sandbox escape in combination with other vulnerabilities.

🟢

If Mitigated

No impact if Chrome is fully patched or if exploit attempts are blocked by security controls.

🌐 Internet-Facing: HIGH

🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes

Weaponized: LIKELY

Unauthenticated Exploit: ⚠️ Yes

Complexity: MEDIUM

Proof-of-concept code is publicly available. Exploitation requires user interaction (visiting malicious site) but no authentication.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 103.0.5060.53 and later

Vendor Advisory: https://chromereleases.googleblog.com/2022/06/stable-channel-update-for-desktop_21.html

Restart Required: Yes

Instructions:

1. Open Chrome. 2. Click menu (three dots) > Help > About Google Chrome. 3. Chrome will automatically check for and install updates. 4. Click 'Relaunch' to restart Chrome with the updated version.

🔧 Temporary Workarounds

Disable WebGL

all

Disables WebGL rendering which prevents exploitation but breaks websites using WebGL.

chrome://flags/#disable-webgl
Set to 'Disabled'

Use Chrome sandboxing

all

Ensure Chrome sandbox is enabled to limit impact if exploited.

chrome://flags/#enable-site-per-process
Ensure enabled

🧯 If You Can't Patch

Block access to untrusted websites using web filtering or firewall rules.
Use application control to restrict execution of unknown processes from Chrome.

🔍 How to Verify

Check if Vulnerable:

Check Chrome version: If version is less than 103.0.5060.53, system is vulnerable.

Check Version:

google-chrome --version (Linux), 'About Google Chrome' in menu (Windows/macOS)

Verify Fix Applied:

Confirm Chrome version is 103.0.5060.53 or higher.

📡 Detection & Monitoring

Log Indicators:

Chrome crash logs with WebGL-related errors
Unexpected Chrome child process termination

Network Indicators:

HTTP requests to domains hosting WebGL exploit code
Unusual outbound connections after visiting suspicious sites

SIEM Query:

source="chrome" AND (event="crash" OR error="WebGL")
