CVE-2022-0452Network attack vector

Sandbox escape via Safe Browsing use-after-free

Published Apr 5, 2022 · Updated Aug 2, 2024

Use-after-free in Google Chrome Safe Browsing before 98.0.4758.80 allows remote attackers to escape the sandbox via crafted HTML. Google identifies the affected component and memory-lifetime error, but the restricted issue does not disclose which object is freed or later reused. Successful exploitation requires a user to load attacker-controlled content and can cross the browser sandbox boundary.
