Sandbox escape via Skia integer overflow
Published Apr 19, 2023 · Updated Oct 21, 2025
Integer overflow in Skia in Google Chrome before 112.0.5615.137 allows remote attackers to escape its sandbox through crafted HTML. The public record does not identify the affected Skia routine or disclose which arithmetic operation wraps on page-controlled input. Exploitation requires user interaction and prior control of the renderer process; escaping the sandbox crosses the browser's isolation boundary.
