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 specially crafted HTML page that exercises the vulnerable WebGL rendering path after an object has been freed and subsequently reused. The available reporting indicates the bug resides in Chrome’s WebGL rendering engine and is reachable remotely through web content. Google states the issue may allow a remote attacker to potentially perform 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 may allow a remote attacker to compromise the browser security boundary and potentially escape Chrome’s sandbox on affected Android versions. Broader Chromium advisories for the same patch set note that vulnerabilities in this release could also contribute to arbitrary code execution, denial of service, or information disclosure, but for CVE-2026-13028 the specifically documented impact is potential sandbox escape via crafted web content.

Mitigation

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

Until patched, reduce exposure by limiting use of untrusted web content on affected Chrome for Android installations and prioritizing rapid browser updates across managed fleets. Enterprise defenders should monitor for renderer instability or crashes involving WebGL contexts as a possible indicator of attempted exploitation. No specific vendor workaround other than updating was provided in the available advisories.

Remediation

Patch, then assume compromise.

Upgrade Google Chrome on Android to version 149.0.7827.197 or later. For Chromium-based downstream products, apply the corresponding vendor patches once available. On Debian chromium systems, apply the patched chromium package versions provided by the distribution for the affected release train.
