CVE-2026-14415Network attack vector

Heap corruption via undisclosed V8 implementation error

Published Jul 1, 2026 · Updated Jul 1, 2026

Inappropriate implementation in V8 in Google Chrome before 150.0.7871.46 allows remote attackers to corrupt heap memory via crafted HTML. The public record identifies V8 as the locus but does not disclose the faulty operation that mishandles attacker-controlled page content. Exploitation requires the user to perform specific UI gestures; the documented consequence is heap corruption, not a demonstrated sandbox escape.
