CVE-2026-65358

Race Condition in State Handling Causes System Termination

Published Sep 14, 2026 CVSS 3.1 · 4.7 Medium EPSS < 1% KEV · Not listed

Description

A race condition was addressed with improved state handling. This issue is fixed in iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, watchOS 27. An app may be able to cause unexpected system termination.

Analysis

Technical impact

A race condition in the state handling of multiple Apple operating systems allows an application to trigger unexpected system termination, resulting in a denial of service. This weakness is a CWE-362 race condition.

Affected Systems

The issue affects Apple iOS 27, iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, and watchOS 27. Devices running older releases remain vulnerable until the listed fixes are applied.

Risk and Exploitability

The CVSS score of 4.7 indicates a medium severity impact on availability. The EPSS score of <1% suggests a very low probability of exploitation in the wild; the vulnerability is not currently listed in CISA's KEV catalog, implying no known widespread exploitation. The race condition can be triggered by an application executing locally that attempts to abuse state handling, leading to an unexpected system termination. While the attack requires local execution, it poses a risk to any user who installs or runs untrusted applications on older unpatched versions.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
