CVE-2025-24224 is a high-severity remote vulnerability affecting Apple iPadOS, as well as other Apple operating systems including tvOS, iOS, macOS Sequoia, watchOS, visionOS, and macOS Ventura. The vulnerability allows a remote attacker to cause unexpected system termination, essentially triggering a denial-of-service (DoS) condition. The root cause relates to insufficient validation or improper handling of certain inputs or operations, classified under CWE-754 (Improper Check for Unusual or Exceptional Conditions). This flaw can be exploited without any authentication or user interaction, and the attack vector is network-based (AV:N), meaning an attacker can trigger the issue remotely over the network. The vulnerability does not impact confidentiality or integrity but severely affects availability by causing system crashes or reboots. Apple addressed the issue by implementing improved checks in the affected OS versions, with patches released in iPadOS 18.5, 17.7.9, iOS 18.5, tvOS 18.5, macOS Sequoia 15.5, watchOS 11.5, visionOS 2.5, and macOS Ventura 13.7.7. No known exploits are currently reported in the wild, but the ease of exploitation and the lack of required privileges or user interaction make this a significant threat, especially for environments relying heavily on iPadOS devices for critical operations.

For European organizations, the impact of CVE-2025-24224 can be substantial, particularly in sectors where iPadOS devices are integral to business operations, such as healthcare, finance, education, and government services. The ability of a remote attacker to cause unexpected system termination can disrupt workflows, cause data loss in volatile memory, and reduce operational availability. This can lead to downtime, loss of productivity, and potential compliance issues under regulations like GDPR if service availability is compromised. Additionally, organizations using iPads as part of their mobile workforce or customer-facing services may face reputational damage if service interruptions occur. Although the vulnerability does not directly expose sensitive data, the denial-of-service effect can be leveraged as part of multi-stage attacks or to distract from other malicious activities.

European organizations should prioritize updating all affected Apple devices to the patched versions as soon as possible, specifically iPadOS 18.5 or 17.7.9 and corresponding updates for other Apple OSes. Network-level protections such as firewalls and intrusion prevention systems should be configured to monitor and restrict suspicious traffic targeting Apple devices, especially from untrusted external sources. Organizations should implement network segmentation to isolate critical iPadOS devices from broader network access. Regular vulnerability scanning and asset inventory management should be employed to identify devices running vulnerable OS versions. Additionally, organizations should educate users on promptly installing OS updates and monitor for unusual device behavior indicative of exploitation attempts. Given the lack of known exploits, proactive patch management is the most effective mitigation. Incident response plans should be updated to include scenarios involving sudden device crashes or DoS conditions on Apple devices.
