CVE-2025-24086 is a vulnerability identified in Apple’s iOS, iPadOS, and several other Apple operating systems, where processing a maliciously crafted image can lead to a denial-of-service (DoS) condition. The root cause is improper memory handling during image processing, which can cause resource exhaustion or crashes, disrupting normal device operation. This vulnerability falls under CWE-770, which involves allocation of resources without proper limits or throttling, enabling attackers to exhaust system resources. Exploitation requires user interaction, such as opening or previewing a malicious image, but does not require elevated privileges or network access, limiting the attack vector primarily to local or user-initiated scenarios. Apple has released patches in multiple OS versions including iOS 18.3, iPadOS 18.3 and 17.7.4, macOS Sequoia 15.3, Sonoma 14.7.3, Ventura 13.7.3, tvOS 18.3, visionOS 2.3, and watchOS 11.3 to address this issue by improving memory handling during image processing. The CVSS v3.1 base score is 5.5 (medium severity), reflecting the limited scope and impact (denial of service only, no confidentiality or integrity impact). There are no known exploits in the wild at this time, but unpatched devices remain vulnerable to potential DoS attacks that could disrupt device availability. This vulnerability is particularly relevant for environments where Apple devices are critical for operations, as service disruption could impact productivity or safety. The vulnerability affects a broad range of Apple platforms, indicating a widespread potential impact across consumer and enterprise devices.

The primary impact of CVE-2025-24086 is denial-of-service, which can cause affected Apple devices to crash or become unresponsive when processing a malicious image. This can disrupt user productivity, cause application failures, or in critical environments, impact operational continuity. Since the vulnerability affects multiple Apple operating systems including iOS, iPadOS, macOS, tvOS, visionOS, and watchOS, a wide range of devices such as iPhones, iPads, Macs, Apple TVs, Vision Pro devices, and Apple Watches are potentially affected. Organizations relying heavily on Apple ecosystems—such as enterprises, healthcare providers, government agencies, and educational institutions—may experience service interruptions if devices are targeted. Although exploitation requires user interaction, attackers could leverage social engineering to trick users into opening malicious images via email, messaging apps, or websites. The lack of confidentiality or integrity impact limits the threat to availability, but repeated or targeted DoS attacks could degrade trust in device reliability. The absence of known exploits reduces immediate risk, but the medium severity score and broad device coverage warrant prompt remediation to prevent potential disruption.

1. Apply the latest security updates from Apple immediately, specifically iOS 18.3, iPadOS 18.3 and 17.7.4, macOS Sequoia 15.3, Sonoma 14.7.3, Ventura 13.7.3, tvOS 18.3, visionOS 2.3, and watchOS 11.3 or later versions. 2. Educate users to avoid opening images from untrusted or unknown sources, especially in emails, messaging apps, or websites. 3. Implement email and web filtering solutions that scan and block malicious image files or suspicious attachments before reaching end users. 4. Restrict or monitor the use of image preview features in enterprise-managed devices where feasible to reduce risk of inadvertent processing. 5. Employ endpoint detection and response (EDR) tools to monitor for abnormal application crashes or device reboots that may indicate exploitation attempts. 6. For critical environments, consider isolating Apple devices from high-risk networks or limiting their exposure to untrusted content. 7. Maintain regular backups and incident response plans to quickly recover from potential DoS incidents. 8. Coordinate with Apple support and security advisories to stay informed about any emerging exploit techniques or additional patches.
