CVE-2024-54522 is a vulnerability identified in Apple’s iOS and iPadOS platforms, where an application with limited privileges can corrupt coprocessor memory due to inadequate bounds checking, categorized as CWE-787 (Out-of-bounds Write). The coprocessor in Apple devices handles specialized processing tasks, and memory corruption here can lead to serious consequences including arbitrary code execution, privilege escalation, or denial of service. The vulnerability does not require user interaction but does require the app to have some level of privilege (PR:L). The attack vector is local (AV:L), meaning the attacker must have the ability to run code on the device, typically through an installed app. The vulnerability affects all versions prior to iOS 18.2 and iPadOS 18.2, as well as related Apple operating systems like macOS Sequoia 15.2, tvOS 18.2, and watchOS 11.2, where the issue has been fixed by implementing improved bounds checks to prevent memory corruption. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No public exploits have been reported yet, but the potential for exploitation exists given the severity and nature of the flaw. This vulnerability poses a significant risk to the security of Apple devices, especially in environments where sensitive data is processed or where device integrity is critical.

The potential impact of CVE-2024-54522 is substantial for organizations relying on Apple devices, including iPhones, iPads, Macs, Apple TVs, and Apple Watches. Successful exploitation could allow malicious apps to corrupt coprocessor memory, leading to arbitrary code execution or system instability, which in turn can compromise device confidentiality, integrity, and availability. This could result in unauthorized data access, persistent malware installation, or denial of service conditions. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that use Apple devices for sensitive operations face increased risk. The local attack vector means attackers need to get an app installed, which could be through malicious or compromised apps distributed outside or inside official app stores. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate it, as attackers may develop exploits over time. Failure to patch could expose organizations to targeted attacks, espionage, or disruption of services.

To mitigate CVE-2024-54522, organizations should immediately update all Apple devices to iOS 18.2, iPadOS 18.2, macOS Sequoia 15.2, tvOS 18.2, watchOS 11.2, or later versions where the vulnerability is fixed. Beyond patching, organizations should enforce strict app vetting policies, limiting app installations to trusted sources such as the official Apple App Store and employing Mobile Device Management (MDM) solutions to control app permissions and installations. Monitoring for unusual app behavior or memory corruption indicators can help detect exploitation attempts. Employing runtime protections and sandboxing features inherent in Apple OS can reduce exploitation risk. Educate users about the risks of installing apps from untrusted sources. For high-security environments, consider restricting device usage policies or deploying endpoint detection and response (EDR) tools capable of identifying anomalous activities related to memory corruption. Regularly review and update security policies to incorporate emerging threat intelligence related to Apple platform vulnerabilities.
