CVE-2026-87464 is a critical use-after-free vulnerability in Google Chrome's WebGL component. Chrome versions prior to 153.0.8010.36 are affected. A remote attacker can trigger the memory-lifetime error by causing a victim to load crafted HTML content, resulting in arbitrary code execution outside the Chrome browser sandbox. Technical details of the underlying flaw are not publicly available because the associated Chromium issue is restricted.
