Published Nov 4, 2025 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 macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, macOS Tahoe 26.1. An app may be able to access sensitive user data.

Analysis

AI-generated

Technical impact

A race condition in macOS may permit an application to read user data that should otherwise be inaccessible. The flaw originates from state handling that fails to serialize concurrent operations correctly, allowing sensitive data to be accessed via a timing exploit. Attackers could obtain personal or confidential information if the condition is triggered.

Affected Systems

Apple macOS versions prior to Sequoia 15.7.2, Sonoma 14.8.2, and Tahoe 26.1 are affected. All earlier releases in these macOS families remain vulnerable, while updated releases implement improved state handling that resolves the race condition.

Risk and Exploitability

The CVSS score of 4.7 indicates a moderate severity, and the EPSS score of <1% suggests a very low likelihood of real‑world exploitation. The flaw is not listed in CISA’s KEV catalog. Based on the description, it is inferred that the attack vector is local, requiring an application with elevated privileges or a user‑injected timing attack to trigger the race condition.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade to Sequoia 15.7.2, Sonoma 14.8.2, or Tahoe 26.1 to eliminate the race condition.
  • Enforce Gatekeeper hardening policies and restrict privileged third‑party applications to reduce the chance of exploiting the flaw.
  • Configure audit controls to detect abnormal privileged process execution or data read attempts, and apply any subsequent patches promptly.
