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

CVE-2025-24137 is a type confusion vulnerability (CWE-843) addressed through improved checks in multiple Apple operating systems. It affects iOS prior to version 18.3, iPadOS prior to 18.3 and 17.7.4, macOS Sequoia prior to 15.3, macOS Sonoma prior to 14.7.3, tvOS prior to 18.3, and visionOS prior to 2.3. The flaw allows an attacker on the local network to corrupt process memory, earning a CVSS v3.1 base score of 8.0 (AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

An adjacent network attacker with no privileges can exploit this vulnerability by tricking a user into interacting with malicious content, such as clicking a link or opening a file. Successful exploitation leads to high-impact consequences, including unauthorized access to sensitive data (confidentiality), modification of system resources (integrity), and disruption of services (availability) through process memory corruption.

Apple's security advisories detail mitigations via software updates, with the issue fixed in iOS 18.3 and iPadOS 18.3, iPadOS 17.7.4, macOS Sequoia 15.3, macOS Sonoma 14.7.3, tvOS 18.3, and visionOS 2.3. Security practitioners should prioritize patching affected devices and advise users to avoid interacting with untrusted local network content. Relevant advisories are available at support.apple.com/en-us/122066, 122067, 122068, 122069, and 122072.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation (including fuzzing and type-aware analysis) directly finds type-confusion flaws before deployment.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles can require use of type-safe languages, static typing, and runtime type checks that structurally avoid allocating one type and accessing another.

SI-16 Memory Protection partial match

Memory-protection controls limit the blast radius when a type-confusion access occurs but do not stop the flaw itself.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent type-confusion flaws via safe typing, static analysis, and code review while the control itself addresses many additional weaknesses.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development can detect type-confusion vulnerabilities through fuzzing and static analysis.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates type-safe design and review that can catch type-confusion flaws.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify strong typing and interface contracts that reduce type confusion.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles promote type-safe languages and memory-safety mechanisms that mitigate type confusion.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly forbid unsafe type casts and require static-analysis checks for type confusion.
