CVE-2025-24177 is a null pointer dereference vulnerability (CWE-476) that was addressed through improved input validation in multiple Apple operating systems. The affected software includes iOS versions prior to 18.3, iPadOS versions prior to 18.3 and 17.7.6, macOS Sequoia prior to 15.3, macOS Sonoma prior to 14.7.5, and macOS Ventura prior to 13.7.5. Published on 2025-01-27, it has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

An attacker on the local network can exploit this vulnerability remotely over the network with low attack complexity, requiring no privileges or user interaction. Exploitation leads to a denial-of-service condition, impacting availability while having no effect on confidentiality or integrity.

Apple's security advisories detail the fixes in the specified updates: iOS 18.3 and iPadOS 18.3, iPadOS 17.7.6, macOS Sequoia 15.3, macOS Sonoma 14.7.5, and macOS Ventura 13.7.5.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (including static analysis) directly finds null-dereference bugs before deployment.

Documented development standards and tools can enforce null-safety rules and safe pointer usage.

Engineering principles can mandate defensive coding such as explicit null checks before dereference.
