Ready for another tech tip from TechBrute? Well, here's Greg Doig with another one for you. Apple patches new zero day affecting iPhone, iPad and Macs hey, this is Greg Doig, back with a quick security alert for Apple users. Apple just pushed emergency updates for iPhone, iPad and Mac to fix the new zero day vulnerability that was being actively exploited. The flaw tracked as CVE2025 43300 lives in the Image I O framework and is an out of bounds write in plain terms, it can let attackers corrupt memory and run code they shouldn't be able to run. So who gets the update? If you're on a recent hardware device, look for iOS 18 or iPadOS 18. That covers devices like the iPhone, Xs and later and and modern iPad Pro, air and mini models. Older iPads are covered by ipados 7.1.17. For Macs, updates are rolling out as macOS Sequoia First 15, Sonoma 14, 7.8 and Ventura 13. Apple says the bug was being used in highly targeted attacks. That doesn't mean everyone is being targeted right now, but history shows attackers often reuse a fixable flaw and broaden their campaigns once a patch is available. So this is one you should install sooner rather than later. So how do you update on iPhone and iPad? Go to Settings General and then Software Update. On a Mac, open the Apple menu and choose System Settings. Software Update and turn on automatic updates if you haven't already. And save your work before installing. Some updates require a restart and can take a while. The bottom line? This is a serious, actively exploited vulnerability. Installing Apple security updates is the simplest and most effective defense. If you run multiple Apple devices, update them all as soon as you can. That's it for now. I'll keep an eye out for more details and let you know if researchers publish indicators of compromise or if Apple revises the advisory. Until then, update your devices and stay safe.
