CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
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 at the 45th 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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Mitigating Controls (NIST 800-53 r5) AI
Maintaining separate execution domains for each process structurally eliminates unintended concurrent access to the same shared resources.
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.
Secure SDLC practices directly require proper synchronization primitives and concurrency testing that prevent race conditions.

Security testing can detect race conditions, but does not prevent them at design or coding time.
Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.
Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.
Secure architecture principles require proper synchronization and resource isolation, addressing the root cause of CWE-362.
Secure coding standards explicitly forbid unsafe concurrent access patterns and mandate atomic operations or locks.
Change management reduces introduction of concurrency bugs during updates, yet does not address the weakness itself.
