CVE-2022-42845 is a high-severity vulnerability that affects multiple Apple products, including macOS, iOS, and iPadOS. The vulnerability stems from improper memory handling, which can allow an application with root privileges to execute arbitrary code with kernel privileges. This potentially exposes sensitive data and compromises system integrity. With a CVSS score of 7.2, the severity of this vulnerability necessitates immediate action from organizations that utilize Apple devices.
The vulnerability was published on December 15, 2022, and affects systems running versions prior to the latest patches, including tvOS 16.2, macOS Monterey 12.6.2, macOS Ventura 13.1, macOS Big Sur 11.7.2, iOS 16.2, and iPadOS 16.2. Risk to organizations includes unauthorized access and control over affected devices, which can lead to severe security breaches.
Organizations should prioritize patching immediately. The vulnerability is classified under CWE-787, indicating a potential flaw in memory management. Given the high impact on confidentiality, integrity, and availability, it is crucial to address this flaw within your operational timelines.
As of now, no known exploits have been reported, but the potential for exploitation exists, especially given the nature of the vulnerability. Organizations using Apple products must remain vigilant and ensure that their systems are updated to the latest versions.
Vulnerability Details
The vulnerability was addressed with improved memory handling in Apple's operating systems.
