CVE-2026-64735Network attack vector

Network-filter bypass via inconsistent Kernel UI state

Published Jul 27, 2026 · Updated Jul 27, 2026

Kernel state-management inconsistency in Apple operating systems allows remote attackers to bypass network filters after user interaction. Apple has not disclosed which Kernel user-interface state transition becomes inconsistent or how attacker-controlled input reaches it. Exploitation is remote and unauthenticated but requires user interaction; the bounded consequence is filter bypass with no reported confidentiality or availability impact.
