In short

A flaw in iOS and iPadOS allows an app to write data beyond intended memory boundaries, potentially letting it run malicious code with system-level permissions. This is dangerous because it can give attackers complete control over your device.

Technical detail

An out-of-bounds write vulnerability (CWE-787) in iOS/iPadOS kernel memory handling allows a local application to write beyond allocated buffer boundaries. Exploitation requires a malicious app installed on the device and results in arbitrary code execution with kernel privileges, bypassing normal security protections.
