Use-after-free in WebGL in Google Chrome on Android

IdentifiersCVE-2026-13028CWE-416

CVE-2026-13028 is a critical use-after-free vulnerability in the WebGL component of Google Chrome on Android prior to version 149.0.7827.197. The flaw can be triggered by a remote attacker via a crafted HTML page, causing Chrome to access memory after it has been freed within WebGL processing. According to the provided advisory context, successful exploitation could potentially lead to a browser sandbox escape.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation could allow a remote attacker to compromise the security boundary of the Chrome renderer on affected Android versions and potentially achieve a sandbox escape. The broader vendor context also notes that Chrome vulnerabilities in this release may enable denial of service, remote code execution, and security restriction bypass, but for this specific CVE the explicitly stated impact is potential sandbox escape.

Mitigation

If you can’t patch tonight, do this now.

Until the patch can be applied, reduce exposure by limiting use of untrusted websites and avoiding opening attacker-controlled or suspicious links that could deliver a crafted HTML page. Enterprise defenders can also prioritize rapid browser patch deployment on Android-managed devices. Specific vendor mitigation guidance beyond updating was not provided in the available content.

Remediation

Patch, then assume compromise.

Upgrade Google Chrome on Android to version 149.0.7827.197 or later. Apply the latest Stable channel update provided by Google as it contains the fix for this WebGL use-after-free vulnerability.
