Executive Summary

This vulnerability is a logic issue related to state management in certain Apple operating systems. Specifically, a UDP server socket that is intended to be bound to a local interface may incorrectly become bound to all network interfaces, potentially exposing the service beyond its intended scope.

Impact Analysis

If exploited, this vulnerability could cause a UDP server socket to be accessible on all network interfaces rather than just a local one. This may increase the attack surface by exposing services to unintended networks, potentially allowing unauthorized access or network-based attacks.

Mitigation Strategies

Apply the fixed software updates provided by Apple for affected operating systems, including tvOS 26, macOS Sonoma 14.8, macOS Sequoia 15.7, iOS 18.7 and iPadOS 18.7, visionOS 26, watchOS 26, macOS Tahoe 26, iOS 26, and iPadOS 26.
