CVE-2025-30444Network attack vector

System termination via SMB mounting race

Published Mar 31, 2025 · Updated Jun 23, 2026

Race condition in Apple macOS Ventura before 13.7.5, Sonoma before 14.7.5, and Sequoia before 15.4 allows remote attackers to terminate the system. The SMB network-share mounting path fails to synchronize shared state correctly while processing a crafted share, allowing concurrent operations to race. The target must mount the attacker-controlled share; successful exploitation interrupts the host by terminating the operating system.
