CVE-2022-32911 is a high-severity vulnerability affecting Apple iOS and related operating systems such as macOS Monterey 12.6, iOS 15.7, iPadOS 15.7, iOS 16, and macOS Big Sur 11.7. The vulnerability stems from improper memory handling, classified under CWE-787 (Out-of-bounds Write). This flaw allows a malicious application to execute arbitrary code with kernel privileges, which means the attacker can gain the highest level of control over the affected device's operating system. The vulnerability requires local access with low privileges (PR:L) but does not require user interaction (UI:N) to be exploited. The attack vector is local (AV:L), indicating that the attacker must have some form of access to the device, such as installing a malicious app or exploiting another local vector. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability (all rated high). The vulnerability was addressed by Apple through improved memory handling in the specified OS versions. No known exploits in the wild have been reported to date, but the potential for severe impact remains significant due to the ability to execute code at the kernel level, which could lead to full device compromise, data theft, persistent malware installation, or disruption of device functionality.

For European organizations, this vulnerability poses a significant risk, especially for enterprises and government agencies that rely on Apple devices for sensitive communications, data storage, and operational tasks. Exploitation could lead to unauthorized access to confidential information, disruption of business operations, and potential lateral movement within corporate networks if compromised devices are connected to internal systems. The ability to execute arbitrary code with kernel privileges could allow attackers to bypass security controls, install persistent malware, or exfiltrate sensitive data. Given the widespread use of Apple devices in Europe, including in sectors such as finance, healthcare, and public administration, the impact could be broad and severe if exploited. Additionally, the lack of required user interaction lowers the barrier for exploitation once local access is obtained, increasing the threat level for organizations with less stringent device management policies.

European organizations should prioritize updating all Apple devices to the patched versions: macOS Monterey 12.6, iOS 15.7, iPadOS 15.7, iOS 16, and macOS Big Sur 11.7 or later. Beyond patching, organizations should implement strict mobile device management (MDM) policies to control app installations and restrict the use of untrusted or unauthorized applications. Employing endpoint detection and response (EDR) solutions capable of monitoring kernel-level activities can help detect anomalous behavior indicative of exploitation attempts. Network segmentation should be enforced to limit the access of mobile devices to critical internal resources. Regular security awareness training should emphasize the risks of installing unverified applications. Additionally, organizations should monitor for indicators of compromise related to kernel-level exploits and maintain incident response plans tailored to potential device-level breaches. Given the local attack vector, controlling physical and logical access to devices is also critical.
