CVE-2026-84620

Integer Overflow in 3D Model Parsing Leads to Memory Corruption

Published Sep 14, 2026 CVSS 3.1 · 7.3 High EPSS < 1% KEV · Not listed
Description
An integer overflow was addressed with improved input validation. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, watchOS 27. Processing a maliciously crafted 3D model may lead to memory corruption.

Analysis

AI-generated

Technical impact

An integer overflow was discovered in the processing of 3D models on Apple devices, leading to memory corruption. This vulnerability arises from improper input validation when parsing maliciously crafted model files, potentially allowing an attacker to overwrite arbitrary memory locations or achieve unintended control flow. The weakness corresponds to known classes of buffer overreach vulnerabilities.

Affected Systems

The flaw affects several Apple operating systems. Fixed versions include iOS 26.OS 26.7 and 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, and watchOS 27. Devices running earlier releases of these platforms are at risk.

Risk and Exploitability

The EPSS score is < 1%, and the vulnerability is not listed in CISA’s KEV catalog, implying that public exploitation data is inferred to involve delivery of a malicious 3D model to a target device, likely via a compromised or malicious application. While the observable severity is high due to potential memory corruption, the absolute risk depends on adoption of older platform versions and the presence of third‑party applications that load such content.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade the operating system on all affected devices to the latest releases that contain the fix.
  • Disable or restrict the use of applications that import or render 3D models until the device is patched.
  • If devices are managed, deploy a policy that blocks or quarantines files capable of triggering the vulnerability until the update is applied.
