CVE-2022-22674 is a medium-severity vulnerability that affects Apple macOS products. This vulnerability allows an out-of-bounds read issue, which may lead to the disclosure of kernel memory to a local user. The issue has been addressed with improved input validation in the latest updates for macOS Monterey, Security Update 2022-004 for Catalina, and macOS Big Sur. Organizations using affected versions are at risk and should prioritize patching to mitigate potential data exposure.
The vulnerability has a CVSS score of 5.5, indicating a medium severity level. The potential impact is significant due to the high confidentiality impact, where sensitive kernel memory could be accessed. As such, organizations should address this vulnerability as part of their security protocols.
This vulnerability was added to the Known Exploited Vulnerabilities (KEV) catalog on April 4, 2022, and organizations are urged to apply the necessary updates as per vendor instructions to protect their systems. Given the nature of this vulnerability, organizations should act swiftly to prevent unauthorized access.
Urgency is critical, as organizations should prioritize patching immediately. Failure to address this vulnerability may lead to severe implications for data integrity and confidentiality.
Vulnerability Details
The official description of CVE-2022-22674 states that an out-of-bounds read issue existed that led to the disclosure of kernel memory. This was addressed with improved input validation. The vulnerability is classified under CWE-125, which pertains to out-of-bounds read issues. It affects macOS products, specifically versions prior to the latest updates including macOS Monterey 12.3.1, Security Update 2022-004 for Catalina, and macOS Big Sur 11.6.6.
The CVSS 3.1 score of 5.5 indicates medium severity. The attack vector is local, with low complexity, and requires low privileges. There is no user interaction required, and the scope remains unchanged. The confidentiality impact is rated high, while integrity and availability impacts are rated as none.
Technical Analysis
The root cause of this vulnerability stems from improper validation of input, which leads to the disclosed memory. Attackers may leverage this vulnerability locally, given that it requires only low privileges. The attack complexity is low, making it easier for potential attackers to exploit it.
The vulnerability impacts the confidentiality of the system since kernel memory can contain sensitive information. However, it does not affect the integrity or availability of the system, limiting the potential damage in certain scenarios.
Risk & Impact Analysis
The real-world risk associated with CVE-2022-22674 is significant, as unauthorized access to kernel memory can lead to sensitive data exposure and potential further exploitation within the system. Organizations utilizing affected macOS versions must consider the implications of this vulnerability on their security posture.
Organizations should prioritize patching this vulnerability immediately, given its inclusion in the KEV catalog and the potential for exploitation in local environments. The urgency is escalated by the ease of potential exploitation due to low complexity and privilege requirements.
