CVE-2026-93372: Google Chrome buffer overflow in WebGL

CVE-2026-93372 · Severity: critical · CVSS 9.6 · Published 2026-09-17

Executive brief

Google Chrome's WebGL graphics engine contains a buffer overflow vulnerability that allows attackers to execute arbitrary code outside the browser sandbox by tricking users into viewing a malicious webpage. This type of attack can lead to complete compromise of the affected device, including theft of data and installation of malware, with no user awareness beyond visiting a link.

Technical details

The vulnerability is a buffer overflow in the WebGL graphics rendering component of Google Chrome on Android. The flaw allows a remote attacker to trigger memory corruption by crafting a malicious HTML page that exploits improper bounds checking in WebGL operations. No authentication or user interaction beyond viewing the page is required; the attack is triggered automatically when the page loads. Successful exploitation results in arbitrary code execution outside the Chrome sandbox, granting the attacker full device-level access. The vulnerability was patched in Chrome version 153.0.8010.52 released on September 17, 2026.
