CVE-2025-43200: iCloud Link Media Processing Vulnerability

Historical catalog analysis: CISA added this entry on June 16, 2025. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2025-43200 is an unspecified vulnerability affecting several Apple operating systems. The flaw is triggered during the processing of a maliciously crafted photo or video file when that media is shared via an iCloud Link. Because this vulnerability has been added to the CISA Known Exploited Vulnerabilities (KEV) catalog, it is recognized as having been exploited in the wild.

Exposure and applicability

The vulnerability is broad in scope, affecting the following Apple product lines:
* iOS
* iPadOS
* macOS
* watchOS
* visionOS

Exposure occurs when a user interacts with a specially crafted media file delivered through the iCloud Link sharing mechanism. Organizations with a high density of Apple mobile and desktop assets, particularly those utilizing iCloud for professional collaboration or data transfer, face the highest applicability.

Remediation priorities

Based on the inclusion of this CVE in the CISA KEV catalog, remediation should be prioritized based on asset exposure to external iCloud Links. Our analysis suggests the following priority sequence:

1. Immediate Patching: Deploy vendor-supplied updates for all affected operating systems (iOS, iPadOS, macOS, watchOS, and visionOS) as specified in Apple’s support documentation.
2. Cloud Service Review: For organizations managing cloud services, review configurations against BOD 22-01 guidance to ensure that the environment is not facilitating the distribution of malicious links.
3. Asset Decommissioning: In rare cases where mitigations are unavailable for legacy hardware that cannot be updated, consider discontinuing use of the product to eliminate the attack vector.

How to validate remediation

Verification must move beyond simple version checks to ensure the mitigation is active and effective across the fleet.

• Deployment Verification: Use Mobile Device Management (MDM) or endpoint management tools to confirm that the specific patched versions identified by Apple are successfully installed on all managed devices.
• Configuration Audit: Verify that cloud service settings align with current security guidance for iCloud Link sharing to reduce the likelihood of accidental exposure.

It is important to note that while a version update indicates the fix has been applied, it does not provide absolute proof that the vulnerability cannot be reached via other unforeseen paths or that the device is immune to similar unspecified flaws.

Limits and open questions

The source provides limited technical detail regarding the root cause of the vulnerability; the specific nature of the memory corruption or logic error remains unknown. Additionally, while CISA has flagged this for active exploitation, it is not currently known if this vulnerability is being utilized by ransomware campaigns. Residual risk remains for users who cannot update their devices due to hardware limitations or those who interact with iCloud Links on unmanaged personal devices used for business purposes.
