CVE-2022-32823 is a medium-severity vulnerability affecting Apple macOS and other Apple operating systems such as iOS, iPadOS, watchOS, and tvOS. The vulnerability arises from a memory initialization issue that could allow a malicious application to leak sensitive user information. Specifically, due to improper memory handling, an app running on an affected system may access uninitialized memory regions, potentially exposing confidential data residing in those memory areas. This vulnerability does not require privileges (PR:N) but does require user interaction (UI:R), meaning that an attacker would need to trick a user into running a malicious app or code. The attack vector is local (AV:L), indicating that the attacker must have local access to the device. The vulnerability impacts confidentiality (C:H) but does not affect integrity or availability. Apple addressed this issue by improving memory handling in the affected OS versions, including iOS 15.6, iPadOS 15.6, macOS Big Sur 11.6.8, macOS Monterey 12.5, Security Update 2022-005 Catalina, watchOS 8.7, and tvOS 15.6. The vulnerability is tracked under CWE-665 (Improper Initialization). No known exploits in the wild have been reported to date. The CVSS v3.1 base score is 5.5, reflecting a medium severity level. The vulnerability's exploitation requires local access and user interaction, limiting its ease of exploitation but still posing a risk especially in environments where untrusted apps can be installed or where users may be tricked into running malicious code. The lack of integrity and availability impact means the threat primarily concerns unauthorized disclosure of sensitive data rather than system disruption or data manipulation.

For European organizations, the primary impact of CVE-2022-32823 is the potential leakage of sensitive user information on Apple devices. Organizations that rely heavily on macOS or other Apple platforms for business operations, especially those handling sensitive or regulated data (e.g., personal data under GDPR, intellectual property, or confidential communications), could face confidentiality breaches if this vulnerability is exploited. The local attack vector and requirement for user interaction reduce the risk of widespread remote exploitation but do not eliminate insider threats or targeted attacks where an attacker can convince a user to run a malicious app. This vulnerability could be leveraged in targeted espionage, data theft, or lateral movement scenarios within corporate networks. The impact is particularly relevant for sectors with high data sensitivity such as finance, healthcare, legal, and government agencies. Additionally, organizations with bring-your-own-device (BYOD) policies or less controlled endpoint environments may be more vulnerable. While no known exploits are currently reported, the presence of this vulnerability in widely used Apple operating systems means that attackers may develop exploits in the future, increasing risk over time. Compliance with data protection regulations in Europe may also be affected if sensitive data leakage occurs due to unpatched systems.

European organizations should prioritize patching affected Apple devices by applying the updates released by Apple for macOS (Big Sur 11.6.8, Monterey 12.5, Security Update 2022-005 Catalina), iOS 15.6, iPadOS 15.6, watchOS 8.7, and tvOS 15.6. Beyond patching, organizations should enforce strict application control policies to prevent installation of untrusted or unsigned applications, reducing the risk of malicious apps exploiting this vulnerability. User education is critical to minimize the risk of social engineering attacks that could trick users into running malicious code. Endpoint protection solutions that monitor for suspicious local activity and memory access patterns can help detect exploitation attempts. Organizations should also review and tighten local access controls and privilege management to limit the number of users who can install or run untrusted applications. For BYOD environments, enforcing mobile device management (MDM) policies that mandate timely OS updates and restrict app installations can reduce exposure. Regular security audits and vulnerability assessments on Apple devices will help ensure compliance and identify unpatched systems. Finally, organizations should monitor threat intelligence feeds for any emerging exploit developments related to CVE-2022-32823.
