CVE-2023-38606 is a medium-severity vulnerability affecting multiple Apple products, including iOS, iPadOS, macOS, tvOS, and watchOS. This vulnerability allows an app to modify sensitive kernel states, potentially leading to unauthorized access or manipulation of system integrity. The CVSS score for this vulnerability is 5.5, indicating a moderate risk to affected systems. It is important for organizations to address this vulnerability to safeguard their systems and data.
Apple has reported that this issue may have been actively exploited against versions of iOS released before iOS 15.7.1. As such, organizations using affected versions should prioritize patching to mitigate the risk of exploitation. The urgency for defenders is critical, as the potential for exploitation can have significant implications for the confidentiality and integrity of systems.
The vulnerability is addressed in the following versions: macOS Monterey 12.6.8, iOS 15.7.8 and iPadOS 15.7.8, iOS 16.6 and iPadOS 16.6, tvOS 16.6, macOS Big Sur 11.7.9, macOS Ventura 13.5, and watchOS 9.6. Organizations should apply these updates immediately to reduce their exposure to potential attacks.
Given the nature of this vulnerability and its potential for exploitation, organizations must remain vigilant and proactive in their security posture. Regular updates and monitoring for known vulnerabilities should be an integral part of any security strategy.
Vulnerability Details
This issue was addressed with improved state management. An app may be able to modify sensitive kernel state. The vulnerability is classified under CVSS 3.1 as having an attack vector of LOCAL, low attack complexity, no privileges required, and requires user interaction.
The affected products include iPadOS, iPhone OS, macOS, tvOS, and watchOS, with a CVSS score of 5.5 indicating a medium level of severity. The publication date of this vulnerability was July 27, 2023.
Technical Analysis
The root cause of this vulnerability stems from inadequate state management within the kernel. Attackers may leverage this vulnerability locally, with low complexity and no required privileges.
