Apple Macos ≤ 15.4
Raw vector
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-24284 is a high-severity Protection Mechanism Failure (CWE-693) vulnerability in Apple Macos. Its CVSS base score is 8.8 (High).
Operationally, ranked at the 2th 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 AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly requires enforcement of access authorizations via the protection mechanism itself.
AC-4 mandates use of information flow enforcement mechanisms to control data movement.
SC-2 requires separation of user and system functionality as a protection mechanism.
SC-28 requires protection mechanisms for information at rest.
SC-3 requires isolation of security functions from non-security functions.
SC-7 requires boundary protection mechanisms to monitor and control external communications.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Systematic verification that security mechanisms operate according to defined standards reduces the likelihood that protection mechanisms are bypassed or disabled.
A.8.26 only requires that security requirements (including protection mechanisms) be identified and specified during development or acquisition; it does not itself mandate, implement, or enforce the mechanisms that would remove CWE-693 instances from the product.
A.8.28 mandates secure coding practices, principles, standards, design, peer review, defect removal, prohibition of insecure techniques (e.g. hard-coded passwords), and evaluation of common errors before deployment, which directly removes many instances of missing or incorrectly used protection mechanisms from first-party code; the bounded remainder is third-party components and post-deployment issues handled by other clauses (8.8, 8.29).
