Successful exploitation could lead to arbitrary code execution or browser crashes. All Chrome users on affected versions are at risk.

📋 TL;DR

This vulnerability allows a remote attacker to trigger a double-free memory corruption in Chrome's WebGL component by tricking users into visiting a malicious webpage. Successful exploitation could lead to arbitrary code execution or browser crashes. All Chrome users on affected versions are at risk.

💻 Affected Systems

Products:

Google Chrome

Versions: All versions prior to 102.0.5005.115

Operating Systems: Windows, macOS, Linux, Android, iOS

Default Config Vulnerable: ⚠️ Yes

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution with the same privileges as the Chrome process, potentially leading to full system compromise if Chrome is running with elevated privileges.

🟠

Likely Case

Browser crash (denial of service) or limited memory corruption leading to unstable browser behavior.

🟢

If Mitigated

No impact if Chrome is fully patched or if WebGL is disabled.

🌐 Internet-Facing: HIGH - Attackers can exploit via malicious websites without user interaction beyond visiting the page.

🏢 Internal Only: MEDIUM - Requires user to visit a malicious internal page, but internal threats could still exploit.

🎯 Exploit Status

Public PoC: ✅ No

Weaponized: UNKNOWN

Unauthenticated Exploit: ⚠️ Yes

Complexity: MEDIUM

Exploitation requires crafting specific WebGL calls to trigger the double-free condition. No public exploit code is known.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 102.0.5005.115 and later

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

Restart Required: Yes

Instructions:

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

🔧 Temporary Workarounds

Disable WebGL

all

Prevents exploitation by disabling the vulnerable component entirely.

chrome://flags → Search 'WebGL' → Set 'WebGL 2.0' to 'Disabled'

Use Chrome sandboxing

all

Ensure Chrome is running with sandboxing enabled to limit impact if exploited.

Verify sandbox is enabled at chrome://sandbox

🧯 If You Can't Patch

Restrict access to untrusted websites using web filtering or proxy rules.
Implement application whitelisting to prevent execution of malicious code from browser exploits.

🔍 How to Verify

Check if Vulnerable:

Check Chrome version in Settings → About Chrome. If version is below 102.0.5005.115, it is vulnerable.

Check Version:

On Windows: chrome://version | On Linux: google-chrome --version | On macOS: /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version

Verify Fix Applied:

Confirm Chrome version is 102.0.5005.115 or higher after update.
