CVE-2025-24211 is a critical memory corruption vulnerability affecting Apple’s iOS, iPadOS, macOS, tvOS, and visionOS platforms. The vulnerability arises from improper memory handling when processing specially crafted video files. An attacker can exploit this flaw by delivering a malicious video file to a target device, which when processed, may cause unexpected application termination or corrupt the process memory. This corruption can lead to denial of service or potentially arbitrary code execution, compromising confidentiality, integrity, and availability of the affected system. The vulnerability requires no privileges or user interaction, making it highly exploitable remotely, for example via malicious media files received through messaging apps, email, or web content. Apple has fixed the issue by improving memory handling in the affected components, releasing patches in iOS 18.4, iPadOS 18.4, macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.4, and visionOS 2.4. The CVSS v3.1 base score is 9.8, reflecting the critical nature of the vulnerability with network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. Although no public exploits are known yet, the vulnerability’s characteristics make it a high priority for patching and monitoring. The CWE-400 classification indicates a resource exhaustion or memory handling issue. Organizations using Apple devices should ensure timely deployment of the patches and consider additional monitoring for suspicious video files or abnormal app crashes.

The impact of CVE-2025-24211 is severe for organizations globally that use Apple devices, including iPhones, iPads, Macs, Apple TVs, and visionOS devices. Exploitation can lead to denial of service through app crashes or more critically, arbitrary code execution allowing attackers to execute malicious code with the privileges of the affected application. This can result in data breaches, unauthorized access, disruption of business operations, and potential lateral movement within networks. The vulnerability’s ease of exploitation without user interaction or privileges increases the risk of widespread attacks, especially via common vectors like messaging apps, email attachments, or web content. Enterprises in sectors such as finance, healthcare, government, and critical infrastructure that rely heavily on Apple ecosystems are at heightened risk. Additionally, the potential for memory corruption raises concerns about persistent compromise and stealthy malware deployment. The broad range of affected Apple operating systems amplifies the scope and scale of potential impact worldwide.

To mitigate CVE-2025-24211, organizations must prioritize immediate deployment of the security updates released by Apple for iOS 18.4, iPadOS 18.4, macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.4, and visionOS 2.4. Beyond patching, organizations should implement network-level filtering to block or inspect suspicious video file formats commonly exploited in attacks. Endpoint detection and response (EDR) tools should be configured to monitor for unusual app crashes or memory corruption indicators. User education should emphasize caution when opening unsolicited video files or links, even though user interaction is not required for exploitation. Employing application sandboxing and restricting app permissions can limit the impact of exploitation. Regularly auditing and updating media processing libraries and frameworks can help prevent similar vulnerabilities. Finally, organizations should maintain comprehensive backups and incident response plans to quickly recover from potential exploitation.
