CVE-2026-17841Network attack vector

UI spoofing via undisclosed interface race

Published Jul 30, 2026 · Updated Jul 30, 2026

Race condition in Chrome for iOS before 151.0.7922.72 allows remote attackers to spoof browser UI through a crafted HTML page. The restricted Chromium issue leaves the raced operation and affected UI state undisclosed, beyond locating the flaw in Chrome for iOS. A user must open the crafted page and interact with the spoofed interface; the reported consequence is deceptive UI content, not code execution or data disclosure.
