Google patched CVE-2025–10585, a Chrome V8 zero-day under active exploitation — here’s what it is, why it matters, and how to stay safe.
Google has released an out-of-band patch this week for CVE-2025–10585, a serious type-confusion vulnerability in Chrome’s V8 JavaScript / WebAssembly engine.

Why This Matters 🌐
Browsers are the most exposed software on most endpoints. They parse untrusted content from every corner of the web — ads, iframes, scripts, user uploads — and V8 is the engine that executes that content in Chrome. A reliable remote code execution (RCE) in V8 lets an attacker turn a single crafted webpage, ad, or compromised third-party script into a delivery mechanism for malware. That’s why V8 bugs get immediate attention, fast patches, and — when exploited — rapid incident responses. 🚨
