CVE-2025-24189 is a high-severity vulnerability affecting Apple visionOS and related Apple platforms including Safari 18.3, iOS 18.3, iPadOS 18.3, macOS Sequoia 15.3, watchOS 11.3, and tvOS 18.3. The vulnerability arises from improper processing of maliciously crafted web content, which can lead to memory corruption. Specifically, this vulnerability is classified under CWE-119, indicating a classic memory safety issue such as a buffer overflow or similar memory handling flaw. Exploitation of this vulnerability does not require any privileges (PR:N) but does require user interaction (UI:R), such as visiting a malicious website or opening crafted web content. The attack vector is network-based (AV:N), meaning an attacker can exploit this remotely without physical access. The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H), allowing an attacker to execute arbitrary code, potentially leading to full system compromise. Apple addressed this issue by implementing improved input validation and memory handling checks in the affected software versions. Although no known exploits are currently reported in the wild, the high CVSS score of 8.8 reflects the significant risk posed by this vulnerability if exploited. Given the widespread use of Apple devices and the integration of visionOS in emerging augmented reality and mixed reality platforms, this vulnerability represents a critical risk vector for users and organizations relying on these technologies.

For European organizations, the impact of CVE-2025-24189 can be substantial. Organizations using Apple visionOS devices or other affected Apple platforms could face risks of unauthorized code execution, data breaches, and service disruptions. This is particularly critical for sectors handling sensitive data such as finance, healthcare, government, and critical infrastructure. The vulnerability could be exploited to gain persistent access, steal intellectual property, or disrupt operations. The requirement for user interaction means phishing or social engineering campaigns could be used to lure users into triggering the exploit. Additionally, as visionOS is designed for immersive experiences, exploitation could lead to manipulation of augmented reality environments, potentially causing physical safety risks or misinformation. The cross-platform nature of the vulnerability (affecting multiple Apple OSes) increases the attack surface within organizations that deploy mixed Apple ecosystems. Given the increasing adoption of Apple devices in European enterprises and public sector, the vulnerability poses a significant threat to confidentiality, integrity, and availability of organizational assets.

European organizations should prioritize patching affected Apple devices and software to versions Safari 18.3, visionOS 2.3, iOS 18.3, iPadOS 18.3, macOS Sequoia 15.3, watchOS 11.3, and tvOS 18.3 or later. Beyond applying patches, organizations should implement strict web content filtering and monitoring to reduce exposure to malicious web content. User awareness training should emphasize the risks of interacting with unknown or suspicious web links, especially in augmented reality contexts. Deploy endpoint detection and response (EDR) solutions capable of detecting anomalous memory corruption behaviors. Network segmentation can limit lateral movement if a device is compromised. Organizations should also review and tighten policies around device usage, especially for visionOS devices in sensitive environments. Incident response plans should be updated to include scenarios involving exploitation of memory corruption vulnerabilities on Apple platforms. Finally, organizations should monitor threat intelligence feeds for any emerging exploit code or attack campaigns targeting this vulnerability.
