CVE-2024-44238

Summary

CVE-2024-44238 is a memory corruption vulnerability affecting the coprocessor in Apple operating systems. The issue arises from improper bounds checking, which could be exploited by a malicious application to write out of bounds and corrupt coprocessor memory.

Exploitation

To exploit this vulnerability, an attacker would need to run a specially crafted app on the device. The attack vector is local, as the app must be installed and executed. No user interaction beyond installing the app is required, and no special privileges are necessary beyond the standard app sandbox.

Impact

Successful exploitation allows an app to corrupt coprocessor memory. This could potentially lead to arbitrary code execution within the coprocessor's context, bypassing security mechanisms. The severity is rated High with a CVSS v3 score of 7.8, indicating significant impact on confidentiality, integrity, and availability.

Mitigation

Apple addressed the issue by implementing improved bounds checks. Fixed versions include iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1. Users are strongly advised to update their devices to the latest software versions to mitigate the risk. [1][2]
