Google releases Chrome 151 security update fixing 382 vulnerabilities, including 15 critical flaws

Google released Chrome 151 with security fixes for 382 browser vulnerabilities affecting Chrome users across supported platforms. Google says 15 of the bugs are rated critical and 67 high severity; many involve memory-safety issues such as use-after-free, type confusion, out-of-bounds access, and input-validation flaws in the renderer that can be triggered by crafted web content and may allow code execution in the browser sandbox or help attackers escape it. No in-the-wild exploitation was disclosed for this batch.
Why it matters: Chrome is one of the most widely used pieces of software, so a large patch batch with multiple critical bugs is broadly important even without confirmed active exploitation. Users and organizations should update browsers promptly through normal patch channels to reduce exposure to malicious websites and drive-by attacks.
