CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-24237 is a critical-severity Classic Buffer Overflow (CWE-120) 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 in the top 28% of CVEs by exploit likelihood; 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 SI-10 (Information Input Validation) — 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.
A buffer overflow vulnerability, tracked as CVE-2025-24237 and assigned CWE-120, was addressed through improved bounds checking in multiple Apple operating systems. The issue affects iOS and iPadOS prior to 18.4, iPadOS prior to 17.7.6, macOS Sequoia prior to 15.4, macOS Sonoma prior to 14.7.5, macOS Ventura prior to 13.7.5, visionOS prior to 2.4, and watchOS prior to 11.4. It carries a CVSS 3.1 score of 9.8.
An unauthenticated attacker can exploit the flaw over a network connection without user interaction to trigger the buffer overflow. Successful exploitation allows an app to cause unexpected system termination, consistent with the high confidentiality, integrity, and availability impacts reflected in the CVSS vector.
Apple security advisories at the listed support URLs detail that the vulnerability is resolved in the updated releases noted above, and organizations should apply those patches to eliminate the exposure.
The associated EPSS score rose from a low baseline to a peak of 0.0245 on 2026-04-03 before receding to the current value of 0.0072, indicating a period of increased exploitation interest after disclosure.

Secure coding directly requires bounds-checked memory operations, addressing the root cause of CWE-120.
Security testing in development and acceptance can detect buffer overflows through fuzzing and static analysis, though it does not prevent them at the source.
Secure development life cycle mandates processes that can include input validation and bounds checking to prevent buffer overflows.
Application security requirements can specify input-size validation and safe buffer handling to mitigate classic buffer overflows.
Secure system architecture and engineering principles promote defensive coding patterns that reduce the likelihood of unchecked buffer copies.
