CVE-2025-24129 is a type confusion vulnerability classified under CWE-843 that affects Apple visionOS and other Apple operating systems including iOS 18.3, iPadOS 18.3, macOS Sequoia 15.3, watchOS 11.3, and tvOS 18.3. The vulnerability arises due to improper type checks within the affected systems, allowing a remote attacker to exploit this flaw to cause unexpected application termination, effectively resulting in a denial-of-service (DoS) condition. The vulnerability does not require any privileges or user interaction, and can be triggered remotely over the network, making it relatively easy to exploit. The impact is limited to availability, as there is no indication of confidentiality or integrity compromise. The issue was addressed by Apple through improved type validation checks in the specified OS versions. No public exploits have been reported yet, but the potential for disruption is significant given the widespread use of Apple devices and the emerging adoption of visionOS in AR/VR applications. The vulnerability’s CVSS v3.1 score is 7.5 (High), reflecting the ease of remote exploitation and the high impact on application availability. Organizations running Apple devices, especially those integrating visionOS in their environments, should be aware of this vulnerability and apply patches promptly to prevent potential service disruptions.

For European organizations, the primary impact of CVE-2025-24129 is the potential for denial-of-service attacks that cause unexpected termination of applications running on Apple devices, including those using visionOS and other Apple operating systems. This can disrupt business operations, especially in sectors relying on AR/VR technologies, mobile applications, or critical services hosted on Apple platforms. The lack of confidentiality or integrity impact limits data breach risks, but availability disruptions can affect productivity, customer experience, and operational continuity. Organizations in finance, healthcare, manufacturing, and public services that increasingly adopt Apple ecosystems could face operational interruptions. Additionally, enterprises deploying visionOS for innovative applications may experience service instability or downtime. The absence of required authentication or user interaction increases the threat’s severity, as attackers can remotely trigger app crashes without user involvement. Although no known exploits are currently active, the vulnerability’s presence in widely used Apple platforms necessitates proactive mitigation to avoid potential exploitation and service degradation.

1. Immediate patching: Organizations should prioritize updating all affected Apple devices to the fixed OS versions—visionOS 2.3, iOS 18.3, iPadOS 18.3, macOS Sequoia 15.3, watchOS 11.3, and tvOS 18.3—to remediate the vulnerability. 2. Asset inventory: Maintain an accurate inventory of Apple devices and visionOS deployments to ensure all endpoints are identified and updated promptly. 3. Network segmentation: Isolate critical Apple devices and visionOS systems within segmented network zones to limit exposure to remote attacks. 4. Monitoring and alerting: Implement monitoring for abnormal application crashes or unexpected terminations on Apple devices to detect potential exploitation attempts early. 5. Incident response readiness: Prepare response plans specifically addressing denial-of-service scenarios caused by app crashes on Apple platforms. 6. Vendor communication: Stay informed through Apple security advisories and CVE databases for any updates or emerging exploit reports related to this vulnerability. 7. User awareness: Educate users on promptly reporting unusual app behavior or crashes to facilitate rapid incident detection and response. 8. Restrict network access: Where possible, restrict inbound network access to Apple devices running vulnerable OS versions until patches are applied to reduce attack surface.
