CVE-2022-0304Network attack vector

User-assisted heap corruption via Bookmarks use-after-free

Published Feb 12, 2022 · Updated Aug 2, 2024

Use-after-free in Google Chrome's Bookmarks component before 97.0.4692.99 allows remote attackers to corrupt heap memory via crafted HTML. The Bookmarks code accesses memory after its object has been freed, but Google keeps the affected object and precise lifetime error undisclosed. Reaching the flaw requires a user to perform specific interactions with the page, and the documented consequence is heap corruption rather than confirmed code execution.
