CVE-2024-54508 is a vulnerability identified in Apple tvOS and related Apple platforms, caused by improper memory handling when processing maliciously crafted web content. This flaw can be triggered remotely without any authentication or user interaction, leading to an unexpected process crash, effectively causing a denial-of-service (DoS) condition. The vulnerability affects multiple Apple operating systems and applications including tvOS, watchOS, visionOS, macOS Sequoia, Safari, iOS, and iPadOS, indicating a shared component or similar codebase susceptible to this issue. The root cause is related to memory management errors that allow crafted web content to destabilize the process handling the content, resulting in a crash. Apple has released fixes in versions tvOS 18.2, watchOS 11.2, visionOS 2.2, macOS Sequoia 15.2, Safari 18.2, iOS 18.2, and iPadOS 18.2, which improve memory handling to mitigate the vulnerability. The CVSS v3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) reflects that the vulnerability is remotely exploitable over the network with low attack complexity, requires no privileges or user interaction, and impacts availability but not confidentiality or integrity. No known exploits are currently reported in the wild, but the potential for denial of service makes timely patching critical.

For European organizations, the primary impact of CVE-2024-54508 is the risk of denial-of-service conditions on Apple TV devices and other affected Apple platforms. This can disrupt media streaming services, digital signage, or any enterprise applications relying on Apple TV infrastructure. While the vulnerability does not compromise data confidentiality or integrity, the availability impact can affect user experience and operational continuity, especially in environments where Apple TV devices are integrated into conference rooms, retail displays, or public information systems. The lack of required authentication and user interaction means attackers can exploit this vulnerability remotely, increasing the risk of widespread disruption. Organizations in sectors such as media, entertainment, education, and retail that utilize Apple TV devices extensively may face operational challenges if devices crash unexpectedly. Additionally, the vulnerability affects multiple Apple platforms, so organizations with mixed Apple device environments need to ensure comprehensive patch management to avoid partial exposure.

European organizations should immediately prioritize updating all affected Apple devices and software to the patched versions: tvOS 18.2, watchOS 11.2, visionOS 2.2, macOS Sequoia 15.2, Safari 18.2, iOS 18.2, and iPadOS 18.2. Network segmentation can help limit exposure of Apple TV devices to untrusted networks, reducing the attack surface. Deploying web content filtering or proxy solutions that inspect and sanitize web content before it reaches Apple devices can mitigate the risk of malicious content triggering the vulnerability. Monitoring device logs and network traffic for unusual crashes or repeated process failures can provide early detection of exploitation attempts. Organizations should also review and enforce strict access controls on management interfaces of Apple devices to prevent unauthorized configuration changes. Regular vulnerability scanning and asset inventory updates will ensure all affected devices are identified and patched promptly. Finally, educating IT staff about this vulnerability and the importance of timely patching will support effective risk management.
