What is CVE-2024-27815?

CVE-2024-27815 is a critical vulnerability identified in various Apple operating systems, including iOS 17.5, iPadOS 17.5, macOS Sonoma 14.5, tvOS 17.5, watchOS 10.5, and visionOS 1.2. This security flaw concerns an out-of-bounds write issue that can enable applications to execute arbitrary code with kernel privileges. Such capabilities can severely undermine the integrity and confidentiality of data on affected devices, posing significant risks to organizations that rely on Apple’s ecosystem for their operations.

Technical Details

The vulnerability stems from inadequate input validation that allows for out-of-bounds writes, which can lead to memory corruption issues. This flaw enables attackers to manipulate memory beyond the intended bounds set by the application. When exploited, it can result in unauthorized access to sensitive information, control over the system, and potential execution of malicious code at a kernel level. The issue has been addressed in updates that reinforce the input validation processes to mitigate future risks.

Impact of the Vulnerability

  1. Arbitrary Code Execution: The most critical impact of CVE-2024-27815 is the potential for attackers to execute arbitrary code with kernel privileges, fundamentally circumventing system security measures and allowing full control over affected devices.

  2. Data Integrity Compromise: With the ability to manipulate memory and execute code, attackers can compromise sensitive data integrity, leading to data breaches and unauthorized information access, which can have severe implications for organizations handling confidential information.

  3. System Stability and Reliability Risks: Exploitation of this vulnerability could lead to system crashes or malfunctions, affecting business continuity and operational reliability for organizations utilizing Apple devices in their day-to-day activities.

Affected Version(s)

iOS and iPadOS < 17.5

macOS < 14.5

visionOS < 1.2

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
