CVE-2025-24216 is a vulnerability identified in Apple tvOS and other Apple operating systems such as visionOS, iPadOS, iOS, and macOS, specifically impacting the Safari web browser component. The root cause involves improper memory handling when processing maliciously crafted web content, which can lead to an unexpected crash of the Safari application. This vulnerability is categorized under CWE-508 (Protection Mechanism Failure) and CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer), indicating a memory safety issue that could be exploited to cause denial of service. The vulnerability requires no privileges (AV:N), has low attack complexity (AC:L), does not require authentication (PR:N), but does require user interaction (UI:R) to trigger the crash by visiting a malicious webpage. The scope is unchanged (S:U), and the impact affects availability only (A:L), with no impact on confidentiality or integrity. The CVSS v3.1 base score is 4.3, reflecting a medium severity level. Apple has addressed this issue through improved memory handling in updates released as visionOS 2.4, tvOS 18.4, iPadOS 17.7.6, iOS 18.4, macOS Sequoia 15.4, and Safari 18.4. No known exploits have been reported in the wild to date. The vulnerability could be leveraged by attackers to disrupt services by causing Safari to crash unexpectedly, potentially affecting user experience and availability of applications relying on Safari’s rendering engine on Apple TV and other Apple devices.

For European organizations, the primary impact of CVE-2025-24216 is the potential for denial of service through unexpected Safari crashes on Apple TV and other Apple devices. This can disrupt digital signage, media streaming, and other services relying on Apple TV devices or Safari browsers, leading to operational downtime and user inconvenience. While the vulnerability does not compromise data confidentiality or integrity, the availability impact could affect sectors dependent on continuous media delivery such as broadcasting, retail, and hospitality. Organizations with remote or distributed workforces using Apple devices may experience interruptions in accessing web-based resources if Safari crashes unexpectedly. The lack of known exploits reduces immediate risk, but unpatched systems remain vulnerable to targeted attacks or accidental crashes triggered by malicious web content. The medium severity rating suggests that while the threat is not critical, timely remediation is important to maintain service continuity and prevent potential exploitation.

1. Apply the latest Apple security updates immediately, including tvOS 18.4, Safari 18.4, and other relevant OS patches to ensure the vulnerability is remediated. 2. Implement network-level web filtering to block access to known malicious or untrusted websites that could host crafted web content designed to trigger the crash. 3. Configure Apple TV and other Apple devices to restrict or monitor Safari usage, especially in environments where device usage is critical for business operations. 4. Educate users about the risks of visiting untrusted websites and encourage cautious browsing behavior to reduce the likelihood of triggering the vulnerability. 5. Monitor device logs and crash reports for unusual Safari crashes that may indicate attempted exploitation or accidental triggering of the vulnerability. 6. For high-value or critical deployments, consider isolating Apple TV devices on segmented networks to limit exposure to potentially malicious web content. 7. Maintain an inventory of Apple devices and ensure patch management processes include these platforms to avoid delays in applying critical updates.
