Summary

CVE-2025-24156 is a high-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Apple Macos. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 41th 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 SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — 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-2025-24156 is an integer overflow vulnerability (CWE-190) in macOS, addressed through improved input validation. It affects macOS versions prior to Sequoia 15.3, Sonoma 14.7.3, and Ventura 13.7.3, with a CVSS v3.1 base score of 7.8 (High). The flaw enables an app to elevate privileges, potentially compromising system security.

A local attacker with low privileges (PR:L) can exploit this vulnerability with low attack complexity (AC:L) and no user interaction required (UI:N). Successful exploitation grants high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged security scope (S:U), allowing privilege escalation from an installed or executed app.

Apple security advisories confirm the issue was fixed in macOS Sequoia 15.3, macOS Sonoma 14.7.3, and macOS Ventura 13.7.3 via enhanced input validation. Practitioners should apply these updates promptly to mitigate the risk, as detailed in the referenced support pages.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.

Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.

Input validation enforces bounds on values before arithmetic, stopping the conditions that trigger overflow or wraparound.

finds

Security testing in development can detect integer overflows before release.

prevents

Secure SDLC mandates input validation and arithmetic checks that prevent integer overflows.

degrades

Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.

degrades

Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.

prevents

Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
