Technical Analysis

CVE-2025-43441 is a vulnerability in Apple iOS and iPadOS discovered in 2025, caused by improper memory handling when processing maliciously crafted web content. This vulnerability is classified under CWE-119, indicating a memory safety issue such as a buffer overflow or similar flaw. When a user browses or otherwise processes specially crafted web content, the affected process may crash unexpectedly, leading to denial of service. The vulnerability requires no privileges (AV:N), has low attack complexity (AC:L), does not require authentication (PR:N), but does require user interaction (UI:R) such as visiting a malicious website or opening malicious content. The scope is unchanged (S:U), and the impact is limited to availability (A:L), with no impact on confidentiality or integrity. The CVSS v3.1 base score is 4.3, indicating medium severity. Apple addressed this issue by improving memory handling in iOS and iPadOS version 18.7.2. No known exploits have been reported in the wild, but the vulnerability could be leveraged to disrupt device availability, potentially affecting business operations relying on mobile Apple devices. The vulnerability highlights the importance of secure memory management in web content processing components of mobile operating systems.

Potential Impact

For European organizations, the primary impact of CVE-2025-43441 is denial of service on iOS and iPadOS devices caused by process crashes when handling malicious web content. This can disrupt mobile workforce productivity, especially in sectors heavily reliant on Apple devices such as finance, healthcare, and government. While the vulnerability does not allow data theft or code execution, repeated crashes could degrade user experience and availability of critical mobile applications. Organizations with Bring Your Own Device (BYOD) policies or those deploying iPhones and iPads for field operations may face operational interruptions. Additionally, targeted attacks leveraging this vulnerability could be used as part of broader campaigns to disrupt communication or access to mobile services. The lack of known exploits reduces immediate risk, but the widespread use of Apple devices in Europe necessitates prompt patching to mitigate potential denial of service scenarios.

Mitigation Recommendations

1. Immediately update all iOS and iPadOS devices to version 18.7.2 or later, where the vulnerability is fixed. 2. Implement mobile device management (MDM) solutions to enforce timely OS updates and monitor device compliance. 3. Restrict access to untrusted or suspicious web content through network-level web filtering and DNS filtering to reduce exposure to malicious content. 4. Educate users about the risks of interacting with unknown or suspicious links and web content, emphasizing cautious browsing behavior. 5. For critical environments, consider deploying application-layer protections such as sandboxing or containerization for web browsers and apps that process web content. 6. Monitor device logs and crash reports for unusual patterns that may indicate exploitation attempts. 7. Coordinate with Apple support channels for any additional guidance or patches if devices cannot be updated immediately.
