CVE-2026-28906Network attack vector

IP-address tracking via undisclosed networking state flaw

Published May 11, 2026 · Updated May 11, 2026

Information disclosure in Networking across affected Apple operating systems allows attackers to track users by IP address. Apple identifies state management as the affected mechanism but has not disclosed the specific state or operation that exposes the address. The behavior is network-reachable without privileges or user interaction, and the reported consequence is limited to IP-based tracking.
