What it is

⚠️ An out-of-bounds read could let attackers access memory they shouldn’t! With just the right input, they might trigger arbitrary code execution. 🔥 Think of it like a restaurant serving food from the wrong kitchen. If the server doesn't check the order correctly, the diner could end up with something completely unexpected and potentially harmful! If exploited, a remote attacker could slip malicious code into your device, compromising its integrity and data security. This could result in unauthorized access to sensitive information or even full control over the device—definitely not a tasty outcome!
