CVE-2025-43277

Vulnerability

Overview

CVE-2025-43277 is a memory corruption vulnerability that exists in the audio file parsing component of multiple Apple operating systems. The root cause is improper memory handling when processing audio files, which can lead to memory corruption if a specially crafted file is opened. Apple addressed the issue with improved memory handling in the security updates [1].

Exploitation

Vector

The attack vector for this vulnerability is through processing a maliciously crafted audio file. An attacker would need to deliver the file to a target user, likely via a website, email attachment, or other file-sharing method. No additional privileges or specific user actions beyond opening the file are required to trigger the condition, making it a high-severity issue [1][2].

Impact

Successful exploitation could allow an attacker to corrupt memory, which may lead to arbitrary code execution in the context of the application processing the audio file. The impact described in Apple's advisory states that 'processing a maliciously crafted audio file may lead to memory corruption,' which can potentially be leveraged for further system compromise [1].

Mitigation

Apple has released security updates for affected platforms: iOS 18.6, iPadOS 18.6, macOS Sequoia 15.6, macOS Sonoma 14.8, tvOS 18.6, visionOS 2.6, and watchOS 11.6. Users are strongly advised to install these updates as soon as possible. No workarounds have been provided. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities Catalog as of this writing [1][2][3][4].
