This vulnerability involves a logic flaw in macOS that could allow a malicious application to intercept network connections meant for other processes, potentially leading to unauthorized access to sensitive data or disruption of services. Apple fixed this issue by implementing improved restrictions in macOS Sequoia 15.7.8, Sonoma 14.8.8, and Tahoe 26.6. The CVSS 3.1 base score of 9.8 reflects the vulnerability's critical nature with network attack vector, low attack complexity, no privileges or user interaction required, and full impact on confidentiality, integrity, and availability.

An attacker exploiting this vulnerability could intercept network connections intended for other processes, leading to potential unauthorized disclosure of information, modification of data, or denial of service. The critical CVSS score indicates a high risk of severe impact on affected systems if unpatched.

Apple has released official fixes in macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, and macOS Tahoe 26.6. Users and administrators should apply these updates promptly to remediate the vulnerability.
