CVE-2022-46702 is classified as a medium-severity vulnerability affecting Apple iOS and iPadOS. The vulnerability arises from improper memory handling, which can potentially allow an app to disclose sensitive kernel memory. The CVSS score for this vulnerability is 5.5, indicating a moderate level of risk to affected systems. Organizations using the vulnerable versions should prioritize patching to prevent potential exploitation.
The issue has been addressed in iOS 16.2 and iPadOS 16.2, with the patch now available. The risk to organizations includes unauthorized access to sensitive information stored in kernel memory. Given the nature of the vulnerability and its potential impact, organizations are advised to implement the necessary updates promptly.
As of now, no known exploits are available, and the vulnerability is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, the presence of high confidentiality impact necessitates a proactive approach to remediation.
Organizations should prioritize patching immediately. The updated versions of iOS and iPadOS can be obtained directly from Apple. This vulnerability serves as a reminder of the importance of regular updates and security patches.
Vulnerability Details
The vulnerability was addressed with improved memory handling, as confirmed by Apple. The official description states: 'An app may be able to disclose kernel memory.' The issue has been classified under CWE-200, indicating information exposure. The CVSS vector for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N, reflecting its attack vector as local, with low attack complexity and no privileges required.
The affected products include iOS and iPadOS, specifically versions 16.0 to prior to 16.2. The publication date of the vulnerability was December 15, 2022.
Technical Analysis
The root cause of CVE-2022-46702 lies in improper memory handling within the affected Apple operating systems. Attackers may leverage this vulnerability to gain access to kernel memory, which contains critical data about the operating system and running applications.
The attack vector is local, meaning an attacker must have physical access to the device to exploit the vulnerability. The complexity of the attack is rated as low, indicating that a successful attack could be executed with minimal effort. No special privileges are required, but user interaction is necessary to execute the malicious application.
The impact on confidentiality is high, as attackers may gain access to sensitive information stored in the kernel memory. However, there is no integrity or availability impact associated with this vulnerability.
Risk & Impact Analysis
Organizations using vulnerable versions of iOS and iPadOS face significant risks due to this vulnerability. If exploited, it can lead to unauthorized disclosure of sensitive information, potentially impacting user privacy and system security.
The blast radius for this vulnerability is limited to devices with the affected software. However, for organizations that rely extensively on Apple products, the consequences of information exposure can be severe, including reputational damage and loss of customer trust.
Given the medium CVSS score of 5.5 and the fact that it is not currently exploited in the wild, organizations should address this vulnerability as part of their priority patch cycle. Regular updates and monitoring for similar vulnerabilities should be part of a comprehensive security strategy.
