CVE-2022-32932 is a high-severity vulnerability affecting Apple iOS and iPadOS operating systems, including versions prior to iOS 15.7.1, iPadOS 15.7.1, iOS 16.1, and iPadOS 16, as well as watchOS 9.1. The vulnerability arises from improper memory handling, classified under CWE-787 (Out-of-Bounds Write), which allows a maliciously crafted app to execute arbitrary code with kernel privileges. Kernel privileges represent the highest level of access on the device, enabling an attacker to bypass security mechanisms, escalate privileges, and potentially take full control of the affected device. Exploitation requires local access (AV:L), meaning the attacker must have the ability to run code on the device, but does not require prior authentication (PR:N). User interaction is necessary (UI:R), implying that the victim must perform some action, such as installing or running a malicious app. The vulnerability impacts confidentiality, integrity, and availability, as arbitrary code execution at the kernel level can lead to data theft, system compromise, persistent malware installation, or device bricking. Although no known exploits in the wild have been reported, the vulnerability's characteristics make it a significant threat if weaponized. Apple addressed the issue by improving memory handling in the kernel, releasing patches in the specified OS versions. The CVSS v3.1 base score is 7.8, reflecting high severity due to the combination of local attack vector, low attack complexity, no privileges required, user interaction, and high impact on confidentiality, integrity, and availability.

For European organizations, this vulnerability poses a substantial risk, especially those with employees or operations relying on Apple mobile devices for sensitive communications, access to corporate networks, or handling confidential data. Successful exploitation could lead to unauthorized access to corporate resources, data leakage, or persistent compromise of devices used for multi-factor authentication or secure communications. Industries such as finance, government, healthcare, and critical infrastructure are particularly vulnerable due to the sensitive nature of their data and regulatory requirements like GDPR. The ability to execute code with kernel privileges could also facilitate lateral movement within enterprise environments if devices are connected to internal networks. Additionally, compromised devices could be used as entry points for espionage or sabotage. The requirement for user interaction limits mass exploitation but targeted attacks against high-value individuals or organizations remain a realistic threat. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks, especially as threat actors develop exploits leveraging this vulnerability.

European organizations should prioritize patching all affected Apple devices by upgrading to iOS 15.7.1, iPadOS 15.7.1, iOS 16.1, iPadOS 16, or watchOS 9.1 or later. Beyond patching, organizations should implement strict mobile device management (MDM) policies to control app installation, restricting devices to trusted app stores and preventing sideloading of unverified applications. Employing endpoint detection and response (EDR) solutions capable of monitoring for anomalous kernel-level activities on Apple devices can help detect exploitation attempts. User awareness training is critical to reduce the risk of social engineering that could lead to installation or execution of malicious apps. Network segmentation should be enforced to limit the access of mobile devices to sensitive internal resources. Additionally, organizations should enforce strong authentication mechanisms and monitor device compliance status continuously. Incident response plans should be updated to include procedures for potential exploitation of mobile device kernel vulnerabilities. Regular audits of device OS versions and patch status should be conducted to ensure timely remediation.
