Understanding CVE-2024-27834: A High Severity Vulnerability in Apple Software

Welcome to LinuxPatch's dedicated security update page. Today, we're unpacking an important security notice regarding CVE-2024-27834, a high severity issue affecting several Apple operating systems and applications. This page aims to provide you with all the necessary information to understand the implications of this vulnerability and encourages immediate action to ensure your systems are updated and secured.

What is CVE-2024-27834?

CVE-2024-27834 has been identified as a concerning vulnerability in Apple's iOS, iPadOS, macOS Sonoma, tvOS, and Safari browser. Scoring a high severity rating of 8.1, the vulnerability exposes the affected systems to significant risk. Specifically, this flaw allows an attacker with arbitrary read and write capabilities to bypass Pointer Authentication, a security feature designed to validate the integrity and authenticity of pointers within the application's memory. This exploitation could potentially lead to further malicious actions such as code execution or access to sensitive information.

What is Pointer Authentication?

Pointer Authentication is an advanced security mechanism used mainly in Apple's operating systems to ensure that pointers (variables used in programming to store memory addresses) have not been tampered with. This is crucial for maintaining the integrity and safety of the system, especially in environments where security is paramount.

Affected Software Versions:

The following versions of Apple software were reported to be vulnerable until updates were released:

  • iOS up until 17.4
  • iPadOS up until 17.4
  • macOS Sonoma up until version 14.4
  • tvOS up until version 17.4
  • Safari up until version 17.4

It is critically important for users and administrators of these systems to ensure they have upgraded to at least iOS 17.5, iPadOS 17.5, macOS Sonoma 14.5, tvOS 17.5, or Safari 17.5, as these versions include the necessary patches and improvements to mitigate this vulnerability.

What You Can Do:

Ensure your software is up-to-date by checking the system settings and applying any outstanding updates promptly. For organizations managing multiple devices, it's recommended to establish a systematic update mechanism using tools like LinuxPatch, which can help streamline and automate the patch management process across diverse Linux server environments. This proactive management helps in safeguarding against vulnerabilities that could compromise the security and integrity of your IT infrastructure.


Security vulnerabilities like CVE-2024-27834 highlight the need for ongoing vigilance and prompt action in the realm of cybersecurity. Ensuring your systems are updated is not only a technical necessity but a critical step in protecting your digital assets against emerging threats.
