Summary

CVE-2025-43244 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 at the 44th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-39 (Process Isolation) and SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

CVE-2025-43244 is a race condition vulnerability (CWE-362) addressed through improved state handling in macOS. It affects macOS Sequoia versions prior to 15.6, macOS Sonoma prior to 14.7.7, and macOS Ventura prior to 13.7.7. The issue enables an app to cause unexpected system termination and carries a CVSS v3.1 base score of 9.8 (Critical), reflecting network accessibility, low complexity, no privileges or user interaction required, and high impacts on confidentiality, integrity, and availability.

A remote, unauthenticated attacker (AV:N/AC:L/PR:N/UI:N) can exploit this race condition by leveraging a malicious app, leading to high confidentiality (C:H), integrity (I:H), and availability (A:H) impacts with unchanged scope (S:U). The primary effect is unexpected system termination, potentially enabling broader disruption.

Apple advisories confirm the vulnerability was fixed in macOS Sequoia 15.6, macOS Sonoma 14.7.7, and macOS Ventura 13.7.7 via improved state handling. Mitigation involves applying these updates, with further details in security content releases at https://support.apple.com/en-us/124149, https://support.apple.com/en-us/124150, https://support.apple.com/en-us/124151, and Full Disclosure mailing list entries at http://seclists.org/fulldisclosure/2025/Jul/32 and http://seclists.org/fulldisclosure/2025/Jul/33.

Mitigating Controls (NIST 800-53 r5) AI

SC-39 Process Isolation partial match

Maintaining separate execution domains for each process structurally eliminates unintended concurrent access to the same shared resources.

SC-4 Information in Shared System Resources partial match

Preventing unintended information transfer through shared system resources directly addresses the improper concurrent modification that defines a race condition.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper synchronization primitives and concurrency testing that prevent race conditions.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect race conditions, but does not prevent them at design or coding time.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles require proper synchronization and resource isolation, addressing the root cause of CWE-362.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly forbid unsafe concurrent access patterns and mandate atomic operations or locks.

A.8.32 Change management none match
none

Change management reduces introduction of concurrency bugs during updates, yet does not address the weakness itself.
