CVE-2026-19137Network attack vector

Sandbox escape via WebGL use-after-free

Published Aug 6, 2026 · Updated Aug 6, 2026

Use-after-free in WebGL in Google Chrome on Android before 151.0.7922.109 allows remote attackers to escape the browser sandbox. WebGL code accesses an object after its memory has been freed, allowing crafted page content to corrupt browser state; Google has not disclosed the affected function or object type. Exploitation requires user interaction with the crafted page and prior compromise of the renderer process, after which the attacker gains execution outside the renderer sandbox.
