CVE-2025-24194 is a logic flaw vulnerability identified in Apple tvOS and other Apple operating systems including visionOS, iOS, iPadOS, and macOS Sequoia. The vulnerability arises from insufficient validation when processing certain crafted web content, which can cause unintended disclosure of process memory. This memory disclosure could reveal sensitive information such as cryptographic keys, user data, or internal application state, potentially aiding further attacks. The issue was addressed by Apple through improved logic checks in the processing pipeline, and fixed in versions tvOS 18.4, visionOS 2.4, iOS 18.4, iPadOS 18.4, and macOS Sequoia 15.4. The CVSS v3.1 score is 6.5 (medium), reflecting that the attack vector is network-based with no privileges required, but user interaction is necessary (e.g., visiting a malicious webpage). The vulnerability impacts confidentiality but does not affect integrity or availability. No known exploits have been reported in the wild, indicating limited current exploitation but a potential risk if weaponized. The flaw affects Apple’s web content processing components, likely WebKit or related frameworks, which are integral to rendering web pages and web-based content on Apple devices including Apple TV. Given the widespread use of Apple devices in consumer and enterprise environments, this vulnerability could be leveraged for targeted information disclosure attacks or reconnaissance.

For European organizations, the primary impact of CVE-2025-24194 is the potential unauthorized disclosure of sensitive information from Apple tvOS devices and other Apple platforms. This could compromise confidentiality of corporate data, user credentials, or cryptographic material stored or processed on these devices. Organizations in sectors such as media, broadcasting, hospitality, and corporate environments that utilize Apple TV devices for presentations or digital signage are at risk. The vulnerability could be exploited via malicious web content delivered through phishing or compromised websites, leading to targeted information leaks. Although the vulnerability does not allow code execution or system takeover, the exposure of process memory can facilitate further attacks or data breaches. The lack of known exploits currently reduces immediate risk, but the medium severity score and ease of exploitation via network and user interaction mean organizations should act promptly. Failure to patch could lead to reputational damage, regulatory compliance issues under GDPR if personal data is exposed, and potential lateral movement by attackers leveraging disclosed information.

1. Apply the latest Apple security updates immediately: upgrade all affected devices to tvOS 18.4 or later, and similarly update visionOS, iOS, iPadOS, and macOS to their respective fixed versions. 2. Restrict access to untrusted or unknown web content on Apple devices, especially Apple TV units used in enterprise environments, by implementing network filtering or web content filtering solutions. 3. Educate users about the risks of interacting with suspicious web content and phishing attempts that could trigger this vulnerability. 4. Monitor network traffic and device logs for unusual web requests or memory access patterns that could indicate exploitation attempts. 5. Where possible, disable or limit web content rendering features on Apple TV devices if not required for business operations. 6. Employ endpoint detection and response (EDR) tools capable of detecting anomalous behavior related to memory disclosure or web content processing. 7. Coordinate with Apple support and security advisories to stay informed about any emerging exploits or additional patches. 8. For organizations with high security requirements, consider network segmentation to isolate Apple TV devices from sensitive systems.
