CVE-2026-64717

Published Sep 14, 2026 CVSS 3.1 · 6.3 Medium EPSS < 1% KEV · Not listed

Description

A race condition was addressed with improved state handling. This issue is fixed in iOS 18.7.10 and iPadOS 18.7.10, iOS 26.6 and iPadOS 26.6, macOS Sequoia 15.7.8, macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, watchOS 26.6. An app may be able to cause unexpected system termination or corrupt kernel memory.

Analysis

Technical impact

A race condition in the state handling code of Apple operating systems can cause unexpected system termination or corruption of kernel memory. The flaw allows concurrent state changes to be improperly serialized, giving an application the ability to trigger overlapping operations that leave the kernel in an inconsistent state, potentially compromising system stability and integrity.

Affected Systems

Apple devices running iOS, iPadOS, macOS, tvOS, visionOS, or watchOS prior to the patch releases that include iOS 18.7.10, iPadOS 18.7.10, macOS Sequoia 15.7.8, macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, or watchOS 26.6. All earlier versions are vulnerable.

Risk and Exploitability

The CVSS score of 6.3 indicates moderate severity, and the EPSS score of less than 1% suggests a low current likelihood of exploitation. The flaw is not listed in the CISA KEV catalog. Exploitation would likely require a locally installed or compromised application that can trigger the race condition through coordinated state changes; thus, the attack vector appears to be local or bounded to trusted code execution.

Affected Products

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

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Apply the latest available OS update that includes the patch—iOS 18.7.10 or later, iPadOS 18.7.10 or later, macOS Sequoia 15.7.8 or Tahoe 26.6, tvOS 26.6, visionOS 26.6, or watchOS 26.6.
Restart the device after updating to guarantee that the kernel state is refreshed and no corrupted memory remains.
Ensure all third‑party applications are updated to the latest compatible versions; avoid known regressions that may re‑introduce the race.
