CVE-2024-5835Network attack vector

Heap corruption via stale tab-group menu pointers

Published Jun 11, 2024 · Updated Feb 13, 2025

Heap buffer overflow in Tab Groups in Google Chrome before 126.0.6478.54 allows remote attackers to corrupt heap memory via crafted HTML. Open menus can retain saved tab groups deleted remotely, and their commands dereference stale pointers to those deleted groups. Exploitation requires the page to load and the user to perform specific UI gestures; the resulting corruption can crash the browser.
