CVE-2024-27828 is a memory handling vulnerability in the IOSurface component of Apple operating systems including iOS, iPadOS, and visionOS. It allows a local application to execute arbitrary code with kernel privileges, which could lead to full system compromise. The vulnerability was fixed by Apple through improved memory handling in iOS 17.5, iPadOS 17.5, and visionOS 1.2. This fix is part of a broader security update addressing multiple vulnerabilities affecting kernel-level components and media processing frameworks. The vulnerability has a CVSS v3.1 score of 7.0, with attack vector local, high attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability. The vendor advisory confirms the availability of an official fix and no known exploits in the wild.

If exploited, this vulnerability allows a local app to execute arbitrary code with kernel privileges, potentially leading to complete system compromise including unauthorized access to sensitive data, system integrity violations, and denial of service. The CVSS score of 7.0 reflects a high impact on confidentiality, integrity, and availability. However, exploitation requires local access and user interaction, and no known exploits have been reported in the wild.

Apple has released official fixes for this vulnerability in iOS 17.5, iPadOS 17.5, tvOS 17.5, visionOS 1.2, and watchOS 10.5. Users and administrators should apply these updates promptly to mitigate the risk. Since the vendor advisory confirms the availability of patches, no additional mitigation steps are required beyond updating to the fixed versions.
