CVE-2025-43364
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA race condition was addressed with additional validation. This issue is fixed in macOS Sequoia 15.7, macOS Sonoma 14.8, macOS Tahoe 26.1. An app may be able to break out of its sandbox.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA race condition vulnerability in macOS allows a malicious application to escape its sandbox containment. The fix implements additional validation checks to prevent the race condition from being exploited, ensuring proper synchronization or validation before security-critical operations.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed macOS versionOpen Terminal and run: sw_vers -productVersionAffected if The version returned is 14.0 to 14.7.x (Sonoma) or 15.0 to 15.6.x (Sequoia)
-
Confirm macOS build number matches vulnerable rangeRun: uname -a to see kernel version, or About This Mac > System Report > Software > Build NumberAffected if Build number falls within vulnerable macOS 14.x or 15.x builds before the patches
-
Verify sandbox is enabledCheck if sandboxd daemon is running: sudo launchctl list | grep sandboxAffected if Sandbox is disabled (vulnerability requires sandbox to be present to escape) - however, most macOS installations have sandbox enabled by default
If running macOS 14.0-14.7.x or 15.0-15.6.x with sandbox enabled, the environment is affected by this race condition that allows sandbox escape.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped14.815.7
Update macOS to version 15.7 (Sequoia), 14.8 (Sonoma), or 26.1 (Tahoe) or later to apply the vendor patch. No further implementation work is required beyond the OS update.
macOS Sonoma 14.8+ or macOS Sequoia 15.7+ (depending on your current macOS major version)
- Back up your Mac using Time Machine or another backup solution before updating
- Open System Settings (or System Preferences on older macOS versions)
- Navigate to General > Software Update
- Check for updates and install the available update
- For macOS 14.x (Sonoma) users: Install macOS Sonoma 14.8 or later
- For macOS 15.x (Sequoia) users: Install macOS Sequoia 15.7 or later
- Restart your Mac when prompted to complete the installation
- Verify the update was successful by checking System Settings > General > About
