CVE-2024-44282 is an out-of-bounds read vulnerability classified under CWE-125, discovered in Apple’s iOS and iPadOS platforms, as well as other Apple operating systems such as macOS Sequoia, Sonoma, Ventura, tvOS, visionOS, and watchOS. The vulnerability occurs during the parsing of a specially crafted file due to inadequate input validation, which allows the system to read memory beyond the intended buffer boundaries. This memory disclosure can lead to leakage of sensitive user information, compromising confidentiality. The vulnerability does not affect system integrity or availability, and exploitation does not require any privileges or prior authentication, but does require user interaction (e.g., opening or processing a malicious file). Apple has released patches in iOS 17.7.1, iOS 18.1, and corresponding updates for other affected OS versions to correct the input validation logic and prevent the out-of-bounds read. The CVSS v3.1 base score is 6.5 (medium severity), reflecting the network attack vector, low attack complexity, no privileges required, user interaction needed, and high impact on confidentiality. No known exploits have been reported in the wild as of the publication date, but the vulnerability represents a credible risk given the widespread use of Apple devices and the potential sensitivity of leaked information.

The primary impact of CVE-2024-44282 is the unauthorized disclosure of user information, which can compromise user privacy and potentially expose sensitive data such as personal identifiers, credentials, or other confidential information stored or processed by the device. Since the vulnerability can be exploited remotely via a crafted file, attackers could target users through phishing emails, malicious websites, or other vectors that deliver malicious files. The lack of required privileges or authentication lowers the barrier to exploitation, increasing the risk to individual users and organizations relying on Apple devices. While the vulnerability does not affect system integrity or availability, the confidentiality breach could facilitate further attacks such as identity theft, targeted phishing, or social engineering. Organizations with large deployments of Apple devices, especially those handling sensitive or regulated data, face increased risk of data leakage and compliance violations if patches are not applied promptly.

To mitigate CVE-2024-44282, organizations and users should immediately apply the security updates released by Apple for all affected platforms, including iOS 17.7.1, iOS 18.1, macOS Sequoia 15.1, Sonoma 14.7.1, Ventura 13.7.1, tvOS 18.1, visionOS 2.1, and watchOS 11.1. Beyond patching, organizations should implement strict email and file filtering to block or quarantine suspicious files that could exploit this vulnerability. User awareness training should emphasize caution when opening files from untrusted sources, especially on Apple devices. Network-level protections such as intrusion detection systems (IDS) and endpoint detection and response (EDR) tools should be tuned to detect anomalous file parsing behaviors or suspicious file formats. Additionally, organizations should enforce the principle of least privilege and restrict unnecessary file handling capabilities on sensitive devices. Regular vulnerability scanning and asset inventory management will help ensure all Apple devices are identified and updated promptly.
