CVE-2026-65329 is an authentication flaw in Apple’s Telephony component affecting iOS 26.6.1 on iPhone 11 and later. The issue stems from improper state management in IPSec-related authentication handling, which can allow an attacker in a privileged network position to bypass IPSec authentication. Successful exploitation enables interception of network traffic that should have been protected by IPSec. Apple addressed the issue through improved state management.
