CVE-2024-44244 is a memory corruption vulnerability classified under CWE-787 (Out-of-bounds Write) affecting Apple visionOS and other Apple platforms such as iOS 18.1, iPadOS 18.1, watchOS 11.1, tvOS 18.1, macOS Sequoia 15.1, and Safari 18.1. The root cause is insufficient input validation when processing web content, which can be maliciously crafted to trigger an unexpected process crash. This vulnerability does not allow for code execution or data leakage but results in denial of service by crashing processes handling the web content. The CVSS v3.1 score of 4.3 reflects a medium severity level, with attack vector being network-based (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:R). The scope remains unchanged (S:U), and the impact is limited to availability (A:L) with no confidentiality or integrity impact. No public exploits have been reported yet, but the vulnerability could be leveraged in targeted denial-of-service attacks against visionOS applications or services that render web content. Apple has mitigated the issue by improving input validation in the affected components, and the fix is included in the latest OS releases. Organizations running visionOS or other affected Apple platforms should ensure they upgrade to these patched versions to prevent potential service disruptions.

For European organizations, the primary impact of CVE-2024-44244 is the risk of denial-of-service conditions caused by process crashes when malicious web content is processed on visionOS devices or other affected Apple platforms. This could disrupt business operations relying on AR/VR applications or services running on visionOS, especially in sectors adopting immersive technologies such as manufacturing, healthcare, education, and design. Although the vulnerability does not compromise data confidentiality or integrity, repeated crashes could degrade user experience and productivity. Enterprises using visionOS for customer engagement or internal collaboration might face operational interruptions. Additionally, organizations that integrate visionOS devices with broader IT infrastructure could see indirect impacts if critical services become unavailable. The absence of known exploits reduces immediate risk, but the medium severity rating and ease of triggering via web content necessitate prompt remediation to avoid potential exploitation in phishing or targeted attacks.

1. Apply the latest Apple security updates immediately, specifically visionOS 2.1 and macOS Sequoia 15.1, as well as updates for iOS, iPadOS, watchOS, tvOS, and Safari where applicable. 2. Implement strict web content filtering and monitoring on visionOS devices to detect and block potentially malicious or malformed web content before processing. 3. Educate users about the risks of interacting with untrusted web content, especially in AR/VR environments where visual cues may be less obvious. 4. Employ network-level protections such as secure web gateways and intrusion prevention systems to reduce exposure to malicious web traffic. 5. For organizations deploying visionOS in enterprise environments, consider sandboxing or isolating applications that render web content to limit the impact of potential crashes. 6. Monitor device logs and crash reports for unusual patterns that may indicate exploitation attempts. 7. Coordinate with Apple support for any additional guidance or patches as they become available.
