CVE-2025-43275
Published: 30 July 2025
Summary
CVE-2025-43275 is a critical-severity Race Condition (CWE-362) vulnerability in Apple Macos. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 33.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-25 (Reference Monitor) and SC-39 (Process Isolation).
Deeper analysis
CVE-2025-43275 is a race condition vulnerability, classified under CWE-362, that was addressed through additional validation measures. It affects the macOS sandboxing mechanism in macOS Sequoia prior to version 15.6, macOS Sonoma prior to 14.7.7, and macOS Ventura prior to 13.7.7. The issue enables an app to break out of its sandbox, potentially bypassing designed isolation controls.
With a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), the vulnerability is exploitable over a network with low complexity, requiring no privileges or user interaction. A remote attacker can leverage a malicious app to trigger the race condition, achieving high-impact confidentiality, integrity, and availability violations by escaping sandbox restrictions and accessing unauthorized system resources.
Apple security advisories confirm the issue is fixed in macOS Sequoia 15.6, macOS Sonoma 14.7.7, and macOS Ventura 13.7.7 via additional validation. Practitioners should prioritize updating affected systems, with details available in Apple's support documents at https://support.apple.com/en-us/124149, https://support.apple.com/en-us/124150, and https://support.apple.com/en-us/124151, along with Full Disclosure mailing list entries.

Mandates separate execution domains for processes, directly preventing sandbox escape vulnerabilities like this race condition in macOS.
Requires a reference monitor mechanism to enforce access control policies comprehensively, which the macOS sandbox implements to block unauthorized breakouts.
Directly mandates timely remediation of flaws, such as patching the race condition vulnerability in macOS sandboxing prior to exploitation.
