Summary

CVE-2025-43274 is a medium-severity Missing Encryption of Sensitive Data (CWE-311) vulnerability in Apple Macos. Its CVSS base score is 4.4 (Medium).

Operationally, ranked at the 3th 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 SC-50 (Software-enforced Separation and Policy Enforcement) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Directly enforces sandbox access restrictions so a sandboxed process cannot bypass them to access unauthorized resources.

SC-50 Software-enforced Separation and Policy Enforcement good match
prevent

Provides software-enforced separation and policy enforcement mechanisms that implement and protect sandbox boundaries.

SC-39 Process Isolation partial match
prevent

Ensures process isolation is maintained so a sandboxed process cannot escape its restricted execution environment.

Mitigating Controls (NIST CSF 2.0) AI

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.DS-01 mostly match
prevents

PR.DS-01 directly mandates encryption for data-at-rest and therefore prevents CWE-311 mostly for storage, yet the weakness also spans transmission and other contexts that this single at-rest control leaves unaddressed.

PR.DS-02 partial match
prevents

PR.DS-02 directly eliminates the transmission facet of CWE-311 via mandatory encryption but leaves the storage facet untouched, so each direction rates only partial.

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.

A.5.14 Information transfer partial match
prevents

Explicit rules requiring encryption for sensitive information in transit eliminate the weakness of sending data without cryptographic protection.

A.8.26 Application security requirements partial match
prevents

Explicitly calling for protection of data in transit and at rest, plus secure encryption of communications, drives the implementation of encryption that prevents clear-text exposure of sensitive information.
