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

IdentifiersCVE-2026-13032CWE-416

CVE-2026-13032 is a critical use-after-free vulnerability in the WebGL component of Google Chrome on Android prior to version 149.0.7827.197. According to the provided content, the flaw was discovered internally by Google on 2026-06-13. The vulnerability can be triggered by a crafted HTML page that exercises the vulnerable WebGL code path, causing stale memory to be reused after free. Google states the issue could potentially lead to a sandbox escape. Specific vulnerable functions or code paths are not available in the provided material, and Google reportedly restricted detailed technical information pending broad patch adoption.

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 leverage memory corruption in Chrome’s WebGL engine and potentially escape the browser sandbox on affected Android systems. The broader advisory context for this release notes that Chromium vulnerabilities in this batch may also lead to arbitrary code execution, denial of service, or information disclosure, but for CVE-2026-13032 the specifically stated impact is potential sandbox escape via crafted web content.

Mitigation

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

No specific workaround is provided in the supplied content. Interim risk reduction is limited to minimizing exposure to untrusted web content, restricting access to attacker-controlled HTML pages, and accelerating browser updates across managed Android fleets and any affected Chromium-based products. Because this is a client-side browser flaw in WebGL, disabling or tightly controlling browser use in high-risk environments may reduce exposure until patching is complete, but patching is the primary mitigation.

Remediation

Patch, then assume compromise.

Upgrade Google Chrome on Android to version 149.0.7827.197 or later. For downstream Chromium-based distributions, apply the vendor-provided patched release as it becomes available. The provided Debian advisory for Chromium recommends upgrading to 149.0.7827.196-1~deb13u1 or later patched package versions where applicable.
