Summary

CVE-2024-23225 is a high-severity Out-of-bounds Write (CWE-787) 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 in the top 28% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

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

A memory corruption vulnerability addressed through improved input validation affects multiple Apple operating systems, including iOS 16.7.6 and iPadOS 16.7.6, iOS 17.4 and iPadOS 17.4, macOS Monterey 12.7.4, macOS Sonoma 14.4, macOS Ventura 13.6.5, tvOS 17.4, visionOS 1.1, and watchOS 10.4. The flaw, tracked as CVE-2024-23225 with a CVSS score of 7.8, resides in kernel-level components and is classified under CWE-787.

An attacker who already possesses arbitrary kernel read and write primitives can exploit the issue to bypass kernel memory protections. This local attack requires no user interaction and can lead to full compromise of confidentiality, integrity, and availability on the affected device.

Apple security advisories for the listed updates state that the vulnerability has been mitigated by the improved validation changes shipped in the March 2024 releases. The company notes it is aware of reports indicating the issue may have been exploited in the wild prior to patching.

EPSS scores for the CVE rose from a low baseline to a peak of 0.0197 shortly after disclosure on 2024-03-07 before receding to the current value of 0.0022, indicating a transient increase in observed exploitation interest.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (including fuzzing and bounds checks) finds out-of-bounds write flaws before deployment.

Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.

Input validation can structurally reject or sanitize data that would otherwise trigger an out-of-bounds write.

Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.
