CVE-2022-32914 is a high-severity vulnerability affecting Apple macOS and related operating systems including iOS, watchOS, and tvOS. The vulnerability stems from a use-after-free (CWE-416) memory management flaw within the kernel, which could allow a malicious application to execute arbitrary code with kernel privileges. This means that an attacker who successfully exploits this vulnerability can gain the highest level of control over the affected system, bypassing normal security restrictions. The flaw was addressed by Apple through improved memory management techniques and is fixed in macOS Big Sur 11.7, macOS Monterey 12.6, macOS Ventura 13, iOS 16, watchOS 9, and tvOS 16. The CVSS v3.1 base score is 7.8, indicating a high severity level. The vector string (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) shows that the attack requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), but requires user interaction (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no known exploits in the wild have been reported, the vulnerability poses a significant risk due to the potential for privilege escalation to kernel level. Exploitation would require an attacker to convince a user to run a malicious app locally, which then leverages the use-after-free bug to gain kernel-level code execution.

For European organizations, this vulnerability represents a critical risk especially for those relying on Apple hardware and software ecosystems, including macOS desktops and laptops, iPhones, iPads, and Apple Watches. Successful exploitation could lead to full system compromise, allowing attackers to bypass security controls, access sensitive data, install persistent malware, or disrupt operations. Sectors such as finance, government, healthcare, and critical infrastructure that use Apple devices could face data breaches, espionage, or operational disruptions. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, particularly in environments where users may install untrusted applications or where insider threats exist. The vulnerability also threatens the integrity and availability of systems, potentially causing downtime or data loss. Given the widespread use of Apple devices in Europe, the impact could be broad if patches are not applied promptly.

European organizations should prioritize patching affected Apple operating systems by upgrading to macOS Big Sur 11.7, Monterey 12.6, Ventura 13, iOS 16, watchOS 9, and tvOS 16 as applicable. Beyond patching, organizations should enforce strict application control policies to prevent installation of unauthorized or untrusted apps, especially those requiring elevated privileges. User education is critical to reduce the risk of social engineering that could lead to running malicious apps. Employ endpoint detection and response (EDR) solutions capable of monitoring for suspicious kernel-level activity. Restrict local administrative rights and implement least privilege principles to limit the impact of any local compromise. Regularly audit and monitor Apple device inventories to ensure all systems are up to date. For highly sensitive environments, consider network segmentation to isolate Apple devices and limit lateral movement. Finally, maintain robust backup and recovery procedures to mitigate potential data loss or system disruption.
