Google just dropped a massive Chrome update — and it's a big one.
Chrome 151 patches 382 security vulnerabilities, including 15 rated critical. That's only 47 fewer than last month's record-breaking update. For context, a year ago, Chrome's stable channel update fixed just three vulnerabilities.
The 15 critical bugs are the ones you really need to worry about. Most are use-after-free (UAF) vulnerabilities — a type of memory corruption flaw where the browser continues referencing memory after it's been freed, allowing attackers to hijack that memory and execute malicious code. These affect high-risk components like Extensions, GPU, WebUSB, Browser, Views, Bluetooth, and Chromoting. Attackers can weaponize these for remote code execution and full browser compromise if left unpatched.
Beyond the critical ones, Google fixed 67 high-severity, 169 medium, and 131 low-severity flaws. The full breakdown? 358 of the 382 vulnerabilities were actually found by Google itself.
Why so many?
AI. Google's been using AI-powered tools to find vulnerabilities at scale — and it's working. Modern memory-safety tooling like AddressSanitizer, MemorySanitizer, and fuzzing frameworks are uncovering flaws that would've taken humans years to find.
What you need to do
Update now. The desktop versions are 150.0.7871.46 (Linux) and 150.0.7871.46/.47 (Windows/Mac). Android users should look for 150.0.7871.63.
Most browsers update automatically, but it can take days or weeks. To force it: open Chrome → Settings → About Chrome. It'll check and download the update if available.
No active exploits have been reported for these particular flaws, but given the sheer volume of patches, waiting isn't a great idea.
