CVE-2024-3169Network attack vector

Heap corruption via V8 use after free

Published Jul 16, 2024 · Updated Aug 1, 2024

Use after free in V8 in Google Chrome before 121.0.6167.139 allows remote attackers to corrupt heap memory through a crafted HTML page. The public record identifies V8 and reuse of freed memory but does not disclose the affected routine or the lifetime error that leaves the object reachable. Exploitation requires a user to open attacker-controlled HTML, after which the corruption can compromise browser confidentiality, integrity, and availability.
