What it is

⚠️ An out-of-bounds read might seem innocent, but it’s a sneaky way for attackers to work their magic! 🌪️ Think of it like a waiter dropping a tray of orders but not checking the number of plates before serving — you could end up receiving someone else's meal! 🍽️ If a remote attacker exploits this vulnerability, they could execute arbitrary code on your device, which can lead to anything from unauthorized access to complete control over your iOS or iPadOS device. That’s a serious breach of security that could compromise your data and privacy!
