CVE-2023-3216Network attack vector

Heap corruption via V8 type confusion

Published Jun 13, 2023 · Updated May 5, 2025

Type confusion in V8 in Google Chrome before 114.0.5735.133 allows remote attackers to corrupt heap memory via a crafted HTML page. Google identifies the locus only as V8 and keeps the linked issue restricted, so the incompatible-type access and triggering JavaScript operation are undisclosed. Exploitation requires a user to load the crafted page, and the reported consequence is heap corruption within the browser process.
