Apple Products UDP Socket Binding Vulnerability

A logic vulnerability has been identified in multiple Apple operating systems, including tvOS 26, macOS Sonoma 14.8, macOS Sequoia 15.7, iOS 18.7, iPadOS 18.7, visionOS 26, and watchOS 26. The issue arises from a UDP server socket that is bound to a local interface, which may inadvertently become accessible on all interfaces. This vulnerability could potentially be exploited to disrupt normal network operations or interfere with application communications.

Impact

Exploitation of this vulnerability could lead to unintended network behavior, where a UDP server socket, meant to be restricted to a local interface, is exposed to all interfaces. This could cause confusion in network communications or allow for unauthorized data to be sent or received.
