CVE-2025-31200 is a critical memory corruption vulnerability affecting various Apple products, including iOS, iPadOS, macOS, and tvOS. The CVSS score of 9.8 indicates a severe risk, particularly given that this vulnerability can allow code execution through maliciously crafted media files, specifically when processing an audio stream. This issue was fixed in recent updates: tvOS 18.4.1, visionOS 2.4.1, iOS 18.4.1, and macOS Sequoia 15.4.1.
Apple has acknowledged that this vulnerability may have been exploited in a sophisticated attack targeting specific individuals on iOS, highlighting the urgency for organizations to address this issue. The memory corruption issue arises from inadequate bounds checking, making it possible for attackers to execute arbitrary code.
Organizations should prioritize patching immediately. Failure to do so could lead to severe consequences, including unauthorized access and complete system compromise. The exploitability of this vulnerability is deemed critical, emphasizing the significant threat it poses to users of affected Apple products.
In response to this vulnerability, Apple recommends applying the necessary updates to all affected systems as soon as possible.
Vulnerability Details
The vulnerability allows for code execution when processing an audio stream in a maliciously crafted media file. The official description states that a memory corruption issue was addressed with improved bounds checking. This issue is particularly concerning due to its potential for exploitation in targeted attacks.
The CVSS vector string for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating a network attack vector, low attack complexity, no privileges required, and no user interaction necessary. The impact on confidentiality, integrity, and availability is rated as high.
Technical Analysis
Root cause analysis indicates a failure in bounds checking which leads to memory corruption. The attack vector is network-based, allowing exploitation without physical access to the device. The attack complexity is low, requiring no user privileges, and there is no user interaction needed to trigger the vulnerability.
The confidentiality, integrity, and availability impacts are all rated as high, meaning successful exploitation could lead to sensitive data exposure, unauthorized alteration of data, and disruption of service.
Risk & Impact Analysis
The risk to organizations includes the potential for significant data breaches and unauthorized access to sensitive information. Given the nature of the vulnerability and its exploitation in targeted attacks, the blast radius could be extensive, affecting not only the compromised devices but also the networks they operate within.
