CVE-2025-24251 is a vulnerability identified in Apple’s iOS, iPadOS, and related operating systems that allows an attacker on the same local network to cause unexpected termination of applications. The root cause relates to insufficient validation or checks within the affected software components, classified under CWE-476 (NULL Pointer Dereference), which can lead to application crashes. The vulnerability does not require any privileges or user interaction, making it easier to exploit in local network environments. The attack vector is local network (AV:A), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact is limited to availability (A:H), with no impact on confidentiality or integrity. Apple has released patches in multiple OS versions including iOS 18.4, iPadOS 18.4 and 17.7.6, macOS Sequoia 15.4, Sonoma 14.7.5, Ventura 13.7.5, tvOS 18.4, visionOS 2.4, and watchOS 11.4 to address this issue by implementing improved checks to prevent the unexpected app termination. No known exploits are currently in the wild, but the medium CVSS score of 6.5 reflects the potential for denial-of-service attacks in environments where attackers can access the local network. This vulnerability primarily threatens the availability of applications, potentially disrupting business operations or user experience on Apple devices.

The primary impact of CVE-2025-24251 is denial of service through unexpected app termination, which can disrupt user productivity and critical application availability on Apple devices. Organizations relying heavily on iOS, iPadOS, and macOS platforms may experience interruptions in business processes, especially in environments where multiple users share local networks such as corporate offices, public Wi-Fi, or educational institutions. Although this vulnerability does not expose sensitive data or allow unauthorized access, repeated or targeted exploitation could degrade trust in device stability and availability. Critical services running on affected Apple platforms could be interrupted, potentially impacting sectors like healthcare, finance, and government where Apple devices are prevalent. The requirement for local network access limits remote exploitation but does not eliminate risk in environments with insufficient network segmentation or unsecured Wi-Fi. The absence of known exploits in the wild suggests limited immediate threat but patching remains essential to prevent future attacks.

1. Apply the latest security updates from Apple immediately, including iOS 18.4, iPadOS 18.4 and 17.7.6, macOS Sequoia 15.4, Sonoma 14.7.5, Ventura 13.7.5, tvOS 18.4, visionOS 2.4, and watchOS 11.4. 2. Implement network segmentation to isolate critical Apple devices from untrusted or guest local networks, reducing exposure to local network attackers. 3. Enforce strong Wi-Fi security protocols (WPA3 where possible) and monitor for unauthorized devices on local networks. 4. Educate users about risks of connecting to unsecured or public Wi-Fi networks, especially in sensitive environments. 5. Use endpoint detection and response (EDR) solutions capable of monitoring application crashes and unusual network activity on Apple devices to detect potential exploitation attempts. 6. Regularly audit and update device configurations to minimize unnecessary local network exposure. 7. Consider deploying network intrusion detection systems (NIDS) tuned to detect anomalous local network traffic patterns that could indicate exploitation attempts. These steps go beyond patching by reducing the attack surface and improving detection capabilities.
