CVE-2024-6997Network attack vector

Heap corruption via Tabs use-after-free

Published Aug 6, 2024 · Updated Aug 13, 2024

Use-after-free in Tabs in Google Chrome before 127.0.6533.72 allows remote attackers to corrupt heap memory via a crafted HTML page. The public record identifies the Tabs component but does not disclose which object is freed or how specific UI gestures trigger its reuse. Exploitation requires a user to open attacker-controlled content and perform those gestures; the record establishes heap corruption but no specific post-corruption outcome.
