CVE-2025-24158 is a vulnerability identified in Apple visionOS and other Apple operating systems including iOS, iPadOS, macOS, watchOS, and tvOS. The root cause is improper memory handling when processing web content, which can be exploited by an attacker to cause a denial-of-service (DoS) condition. This vulnerability is classified under CWE-79, indicating issues related to improper input handling that can lead to memory corruption or crashes. The CVSS v3.1 base score is 6.5 (medium severity), with an attack vector of network, low attack complexity, no privileges required, but user interaction is necessary (e.g., visiting a malicious website). The impact is limited to availability, as confidentiality and integrity are not affected. The vulnerability was addressed by Apple through improved memory management in visionOS 2.3, Safari 18.3, and corresponding updates across Apple platforms. No public exploits have been reported, but the potential for denial-of-service attacks exists if users access malicious web content. This vulnerability highlights the risks associated with web content processing engines and the importance of robust memory handling to prevent service disruptions.

For European organizations, this vulnerability primarily threatens availability by enabling denial-of-service attacks that could disrupt user access to critical Apple devices and services. Organizations relying on visionOS devices or Apple browsers in operational environments may experience interruptions, impacting productivity and service continuity. Although the vulnerability does not compromise confidentiality or integrity, repeated or targeted DoS attacks could degrade user trust and operational reliability. Sectors such as finance, healthcare, and government that increasingly adopt Apple technologies for secure and mobile operations could face operational challenges. Additionally, organizations with remote or hybrid workforces using Apple devices are at risk of service disruption. The absence of known exploits reduces immediate risk, but the medium severity rating and ease of triggering via user interaction necessitate proactive patching and user awareness to mitigate potential impact.

1. Immediately apply the security updates released by Apple, including visionOS 2.3, Safari 18.3, iOS 18.3, iPadOS 18.3, macOS Sequoia 15.3, watchOS 11.3, and tvOS 18.3. 2. Implement network-level filtering to restrict access to untrusted or suspicious web content, especially on devices running affected Apple operating systems. 3. Educate users about the risks of interacting with unknown or suspicious web links, emphasizing caution when browsing or clicking links in emails or messages. 4. Employ endpoint protection solutions capable of detecting abnormal application crashes or memory-related anomalies on Apple devices. 5. Monitor device and network logs for signs of repeated crashes or service disruptions that may indicate exploitation attempts. 6. For organizations deploying visionOS devices in critical environments, consider isolating these devices or restricting their web access until patches are applied. 7. Maintain an up-to-date asset inventory of Apple devices to ensure all affected systems are identified and remediated promptly.
