CVE-2026-84620
Apple · iOS, iPadOS, macOS, tvOS, visionOS, watchOS
A memory corruption vulnerability exists in multiple Apple operating systems due to an integer overflow during the processing of maliciously crafted 3D models.
Executive summary
An integer overflow vulnerability in various Apple operating systems allows for memory corruption when processing malicious 3D models, posing a high risk of system compromise.
Vulnerability
This is an integer overflow flaw triggered by improper input validation when parsing 3D model files. The vulnerability requires local user interaction to process the malicious file, leading to potential memory corruption.
Business impact
The vulnerability carries a CVSS score of 7.3, reflecting its potential to cause full system compromise, including confidentiality, integrity, and availability loss. Exploitation could allow an attacker to execute arbitrary code or cause system crashes, which poses a significant risk to organizational data security and operational continuity for users of these devices.
Remediation
Immediate Action: Update all affected Apple devices to the specified versions, including iOS 26.7 or 27, macOS 15.8, 26.7, or 27, and the corresponding updates for tvOS, visionOS, and watchOS.
Proactive Monitoring: Review system logs for unusual application crashes or unexpected behavior related to 3D rendering or file processing tasks.
Compensating Controls: Implement robust endpoint protection software and restrict the opening of untrusted files from unknown or unverified sources to reduce the attack surface.
Exploitation status
Public Exploit Available: No
Analyst recommendation
Given the potential for complete system compromise via memory corruption, organizations should prioritize the deployment of these security updates across their mobile and desktop fleets. Administrators must ensure that all managed Apple devices are updated to the latest available versions to eliminate this risk.
