Apple Memory Corruption in Audio Stream Processing (CVE-2025-31200)

Historical catalog analysis: CISA added this entry on April 17, 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-2025-31200 is a memory corruption vulnerability identified in multiple Apple products. The flaw exists within the processing of audio streams; specifically, an attacker could trigger the vulnerability by inducing the system to process a maliciously crafted media file. Successful exploitation of this memory corruption could lead to arbitrary code execution on the affected device.

Exposure and applicability

This vulnerability affects a broad range of Apple hardware and software ecosystems, including:
* iOS
* iPadOS
* macOS
* Other unspecified Apple products

The primary exposure path is the ingestion of media files containing malicious audio streams. This suggests that any application or system process capable of parsing these file types could serve as an entry point if the underlying vulnerable libraries are utilized.

Remediation priorities

Based on the inclusion of this vulnerability in the CISA Known Exploited Vulnerabilities (KEV) catalog, remediation should be prioritized for devices that frequently handle untrusted media files or operate in high-risk environments. Our analysis suggests the following priority sequence:

1. Immediate Patch Deployment: Apply the specific vendor updates provided by Apple for iOS, iPadOS, and macOS to address the memory corruption flaw.
2. Fleet Identification: Use mobile device management (MDM) or asset inventory tools to identify all Apple devices currently running versions prior to the vendor’s fix.
3. Cloud Service Review: For organizations utilizing Apple services in a cloud context, review configurations against BOD 22-01 guidance as applicable.
4. Decommissioning: If specific legacy hardware cannot be updated to a patched version and no compensating controls are available, consider discontinuing the use of those assets.

How to validate remediation

Verification must move beyond simple version checks to ensure the mitigation is active and effective:
* Patch Confirmation: Verify that the update was not only downloaded but successfully installed across the fleet via MDM reporting or system logs.
* Configuration Audit: Ensure that automatic updates are enabled where possible to reduce the window of exposure for future iterations of similar flaws.

It is important to note that a version number check alone does not prove that the memory corruption is fully mitigated in all operational contexts, as environmental factors can influence exploitability.

Limits and open questions

There are several unknowns regarding this vulnerability. While it is listed in the KEV catalog, the specific original disclosure date remains distinct from the CISA addition date of April 17, 2025. Additionally, it is currently unknown if this vulnerability has been leveraged by known ransomware campaigns.

Residual risk remains for devices that cannot be updated due to hardware limitations or software dependencies. In these cases, the memory corruption flaw persists, and the only remaining reduction in exposure is to limit the device’s ability to process untrusted media files.
