CVE-2024-9602Network attack vector

Out-of-bounds memory write via V8 type confusion

Published Oct 8, 2024 · Updated Nov 20, 2025

Type confusion in V8 in Google Chrome before 129.0.6668.100 allows remote attackers to perform an out-of-bounds memory write via crafted HTML. The public record identifies V8 type confusion as the cause, but the restricted issue does not disclose the affected function or faulty operation. Exploitation requires a user to open the crafted page, and the published record establishes the memory write but does not claim code execution.
