CVE-2025-24154 is a critical vulnerability affecting multiple Apple operating systems, including iOS, iPadOS, macOS, and visionOS. This vulnerability allows an attacker to exploit an out-of-bounds write condition that could lead to unexpected system termination or kernel memory corruption. The vulnerability has been assigned a CVSS score of 9.1, indicating its critical nature and the significant risk it poses to affected systems. Organizations should prioritize patching immediately to mitigate this risk.
The vulnerability was publicly disclosed on January 27, 2025, and affects versions of iOS (18.3), iPadOS (18.3), macOS (Sequoia 15.3, Sonoma 14.7.3, Ventura 13.7.3), and visionOS (2.3). Given the nature of the vulnerability, it presents a high risk of exploitation, and the urgency for organizations to apply the necessary updates cannot be overstated.
As the exploitability of this vulnerability is classified as critical, organizations must take the necessary steps to patch their systems. Failure to do so could result in severe operational disruptions and data integrity issues.
In light of this vulnerability, organizations should also consider implementing additional security measures, such as continuous monitoring and vulnerability assessments, to ensure that their systems remain secure against potential threats.
Vulnerability Details
An out-of-bounds write was addressed with improved input validation. This issue is fixed in iOS 18.3 and iPadOS 18.3, macOS Sequoia 15.3, macOS Sonoma 14.7.3, macOS Ventura 13.7.3, visionOS 2.3. An attacker may be able to cause unexpected system termination or corrupt kernel memory.
The CVSS score for this vulnerability is 9.1, classified as critical, indicating that it poses a significant threat to the confidentiality, integrity, and availability of affected systems. The attack vector is network-based, and the attack complexity is low, meaning that exploitation could be carried out without special conditions. No privileges are required, and no user interaction is necessary.
The affected products include iOS, iPadOS, macOS, and visionOS. The vulnerability has been categorized under CWE-787 (Out-of-Bounds Write) and CWE-757 (Access to Uninitialized Pointer), highlighting the underlying weaknesses exploited by attackers.
Technical Analysis
The root cause of this vulnerability is a failure in input validation that allows for out-of-bounds writes. This can occur when a program fails to validate or restrict the input size, leading to unintended memory access. The attack vector is network-based, making it particularly dangerous as it could be exploited remotely without physical access to the device.
The attack complexity is considered low, meaning that an attacker with minimal technical knowledge could exploit this vulnerability. No privileges are required to carry out the attack, and user interaction is not necessary, which increases the potential impact of this vulnerability.
The impact on confidentiality is rated as none, while the integrity and availability impacts are both rated as high. This means that while sensitive information may not be directly compromised, the overall functionality and performance of the affected systems could be severely disrupted.
Risk & Impact Analysis
The risk to organizations includes potential system termination and kernel memory corruption, which could lead to a loss of functionality and data integrity. As the vulnerability is present in widely used Apple operating systems, the blast radius is extensive, affecting millions of users worldwide. Organizations that rely on these systems are particularly vulnerable to disruptions and data loss.
Given the critical nature of this vulnerability, organizations should address it in their priority patch cycle. The CVSS score of 9.1 highlights the urgency of remediation, and the absence of known exploits does not reduce the importance of immediate action. Proactive monitoring and vulnerability assessments are essential to mitigate the risk of future incidents.

Affected Versions
The vulnerability affects the following products and their versions:
iOS and iPadOS versions prior to 18.3, macOS versions prior to 13.7.3, and visionOS versions prior to 2.3 are vulnerable.
Mitigation & Remediation
To mitigate this vulnerability, organizations should apply the latest patches provided by Apple. Upgrade to iOS 18.3, iPadOS 18.3, macOS Sequoia 15.3, macOS Sonoma 14.7.3, or macOS Ventura 13.7.3, and visionOS 2.3. If immediate patching is not feasible, consider implementing network controls to restrict access to vulnerable systems.
Additionally, organizations should monitor their systems for any signs of exploitation and conduct regular vulnerability assessments to maintain a secure environment.
Detection Guidance
Organizations should monitor their logs for unusual activity that may indicate exploitation of this vulnerability. Look for signs of unexpected system terminations, crashes, or other anomalies that could suggest attempts to exploit this vulnerability.
AppSecure Threat Intelligence Insight
This vulnerability underscores the importance of proactive security measures in software development and deployment. Organizations must prioritize input validation and memory management to prevent such vulnerabilities from being introduced in the first place.
Security teams should also focus on implementing robust testing methodologies, such as penetration testing methodologies to identify and remediate potential vulnerabilities before they can be exploited.
Furthermore, organizations should engage in regular security training for their development teams to ensure they are aware of the latest threats and secure coding practices. This is essential for maintaining the security posture of their applications and systems.
For organizations looking to enhance their security strategies, leveraging external services for security assessments, such as application security assessments, can provide valuable insights and help organizations stay ahead of potential threats.
