CVE-2025-31245 is a vulnerability identified in Apple tvOS that allows an application to cause unexpected system termination, effectively resulting in a denial of service (DoS) condition. The root cause is related to insufficient validation or checks within the system that an app can exploit to crash the operating system unexpectedly. The vulnerability affects multiple Apple operating systems, including tvOS, macOS (Sonoma, Ventura, Sequoia), iPadOS, iOS, and visionOS, with patches released in tvOS 18.5 and corresponding OS versions. The CVSS v3.1 score is 5.5, reflecting a medium severity level. The attack vector is local (AV:L), meaning the attacker must have local access with limited privileges (PR:L) and no user interaction (UI:N) is required. The impact is limited to availability (A:H), with no confidentiality or integrity impact. This vulnerability is categorized under CWE-400, which relates to uncontrolled resource consumption or denial of service. No known exploits are currently reported in the wild, but the vulnerability could be leveraged by malicious or compromised apps to disrupt system availability. The fix involves improved system checks to prevent apps from triggering the unexpected termination. Organizations using Apple TV devices or related Apple OS environments should prioritize patching to mitigate this risk.

For European organizations, the primary impact of CVE-2025-31245 is the potential for denial of service on Apple tvOS devices, which could disrupt operations relying on these devices. This includes digital signage, conference room systems, media streaming in corporate environments, and other integrated Apple TV deployments. While the vulnerability does not compromise data confidentiality or integrity, the availability impact could lead to operational downtime, user frustration, and potential productivity loss. In sectors such as retail, hospitality, education, and corporate offices where Apple TV is used for presentations or customer engagement, this could affect service delivery. The requirement for local access limits remote exploitation, but insider threats or compromised devices could still trigger the issue. The absence of known exploits reduces immediate risk, but unpatched devices remain vulnerable to potential future attacks. European organizations should assess their Apple device usage and ensure timely updates to minimize disruption risks.

To mitigate CVE-2025-31245, European organizations should: 1) Inventory all Apple tvOS devices and related Apple OS platforms in use to identify vulnerable versions. 2) Deploy the official patches released by Apple, specifically updating to tvOS 18.5 or later and corresponding OS versions for other Apple devices. 3) Restrict installation of untrusted or unauthorized applications on Apple TV devices to reduce the risk of local exploitation. 4) Implement strict access controls and monitoring on devices to detect and prevent unauthorized local access. 5) Educate users and administrators about the risk of installing potentially malicious apps that could exploit this vulnerability. 6) Consider network segmentation for Apple TV devices to limit the impact of any potential compromise. 7) Monitor vendor advisories and threat intelligence feeds for any emerging exploit activity related to this CVE. These steps go beyond generic patching by emphasizing device management, access control, and proactive monitoring.
