CVE-2022-32898 is a high-severity vulnerability affecting Apple macOS and other Apple operating systems including iOS and iPadOS. The vulnerability arises from improper memory handling within the kernel, which could allow a malicious application to execute arbitrary code with kernel-level privileges. This means that an attacker who successfully exploits this flaw can gain the highest level of control over the affected system, bypassing all security restrictions and potentially compromising system confidentiality, integrity, and availability. The vulnerability requires local access (attack vector: local) and user interaction, as the attacker must run a malicious app on the device. The vulnerability does not require prior authentication but does require the user to launch or interact with the malicious app. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. Apple addressed this issue by improving memory handling in the kernel, and patches were released in iOS 15.7, iOS 16, macOS Ventura 13, and watchOS 9. No known exploits in the wild have been reported so far. However, the potential for privilege escalation to kernel level makes this vulnerability particularly dangerous if exploited. The vulnerability affects unspecified versions prior to the patched releases, so any unpatched macOS or iOS devices remain at risk.

For European organizations, this vulnerability poses a significant risk especially for enterprises and government entities that rely on Apple devices for critical operations. Successful exploitation could lead to full system compromise, enabling attackers to install persistent malware, steal sensitive data, disrupt services, or move laterally within networks. Organizations in sectors such as finance, healthcare, and public administration, which often use Apple devices, could face data breaches or operational disruptions. The requirement for local access and user interaction somewhat limits remote exploitation, but targeted attacks such as spear phishing or malicious app distribution remain viable vectors. Additionally, the ability to escalate privileges to kernel level could allow attackers to bypass endpoint security solutions, complicating detection and response efforts. The impact on confidentiality, integrity, and availability is high, potentially leading to regulatory and compliance issues under GDPR if personal data is compromised.

European organizations should prioritize patching all affected Apple devices with the updates released by Apple (iOS 15.7, iOS 16, macOS Ventura 13, watchOS 9). Beyond patching, organizations should implement strict application control policies to prevent installation of unauthorized or untrusted apps, especially from outside the official Apple App Store. Endpoint detection and response (EDR) solutions should be tuned to detect suspicious kernel-level activity or unusual privilege escalation attempts. User awareness training should emphasize the risks of installing untrusted applications and the importance of applying system updates promptly. Network segmentation can limit the impact of compromised devices. Additionally, organizations should monitor for indicators of compromise related to kernel exploits and maintain robust incident response plans to quickly contain and remediate any exploitation attempts.
