CVE-2024-54501 is a vulnerability identified in Apple’s iOS, iPadOS, and several other Apple operating systems, including macOS variants, tvOS, visionOS, and watchOS. The vulnerability stems from insufficient validation when processing certain specially crafted files, which can trigger a denial of service (DoS) condition. Specifically, the flaw is categorized under CWE-770, which relates to allocation of resources without limits or throttling, leading to resource exhaustion or system instability. When a user processes a malicious file—such as opening or previewing it—the system may become unresponsive or crash, impacting device availability. The attack vector requires local access (AV:L), no privileges (PR:N), but does require user interaction (UI:R) to trigger the vulnerability. The scope is unchanged (S:U), and the vulnerability does not compromise confidentiality or integrity, only availability (A:H). Apple has released patches in multiple OS versions, including iOS 18.2, iPadOS 18.2 and 17.7.3, macOS Sequoia 15.2, Sonoma 14.7.2, Ventura 13.7.2, tvOS 18.2, visionOS 2.2, and watchOS 11.2, which implement improved input validation and checks to prevent exploitation. There are no reports of active exploitation in the wild at this time.

The primary impact of CVE-2024-54501 is denial of service, which can disrupt the availability of Apple devices by causing system crashes or freezes when processing malicious files. For organizations, this can lead to temporary loss of productivity, interruption of critical communications, and potential operational delays, especially in environments heavily reliant on Apple mobile and desktop platforms. While the vulnerability does not expose sensitive data or allow unauthorized code execution, the forced downtime can be leveraged in targeted attacks to cause disruption. Enterprises with large deployments of iPhones, iPads, Macs, or Apple TVs could face widespread impact if malicious files are distributed internally or via email, messaging, or shared drives. The requirement for user interaction limits remote exploitation but does not eliminate risk, particularly in phishing or social engineering scenarios. The absence of known exploits reduces immediate risk, but the medium severity and broad device coverage warrant prompt remediation.

Organizations should immediately prioritize patching affected Apple devices by upgrading to the fixed OS versions: iOS 18.2, iPadOS 18.2 and 17.7.3, macOS Sequoia 15.2, Sonoma 14.7.2, Ventura 13.7.2, tvOS 18.2, visionOS 2.2, and watchOS 11.2. Beyond patching, implement strict controls on file handling by restricting the types of files that can be opened or previewed on corporate devices, especially those received from untrusted sources. Employ email and messaging gateway filters to detect and block potentially malicious attachments. Educate users on the risks of opening unexpected or suspicious files and encourage verification before interacting with unknown content. Use Mobile Device Management (MDM) solutions to enforce update policies and monitor device compliance. Network segmentation and application whitelisting can further reduce exposure. Regularly review logs for abnormal application crashes that may indicate attempted exploitation. Finally, maintain an incident response plan to quickly isolate affected devices if a DoS event occurs.
