CVE-2025-43275
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 15.6, macOS Sonoma 14.7.7, macOS Ventura 13.7.7. 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 · moderate confidenceA race condition in macOS sandbox implementation allows a malicious application to bypass sandbox restrictions and escape its security context. The fix adds additional validation checks to prevent the race condition from being exploitable. This is a local privilege escalation vulnerability affecting the macOS sandbox subsystem.

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.
-
Check installed macOS version via System SettingsOpen System Settings, go to General > About, and note the Version number (e.g., 14.6.1, 15.5, 13.7.6)Affected if The version falls within any of these ranges: < 13.7.7 (Ventura), >= 14.0 and < 14.7.7 (Sonoma), >= 15.0 and < 15.6 (Sequoia)
-
Check installed macOS version via command lineRun 'sw_vers -productVersion' in TerminalAffected if The output version is less than 13.7.7, between 14.0-14.6.x, or between 15.0-15.5.x
-
Verify if security update is installedRun 'system_profiler SPSoftwareDataType' and look for the macOS version and security updates installedAffected if The system shows a version before the patched releases (13.7.7, 14.7.7, or 15.6) with no corresponding security update applied
A system is affected if it runs macOS Ventura below 13.7.7, Sonoma between 14.0-14.6.x, or Sequoia between 15.0-15.5.x, and has not received the corresponding security update.

Apply the appropriate macOS security update: Sequoia 15.6, Sonoma 14.7.7, or Ventura 13.7.7. This is an Apple OS-level vulnerability that has been patched; no third-party remediation is required.
macOS Ventura 13.7.7, macOS Sonoma 14.7.7, or macOS Sequoia 15.6 (depending on your current macOS major version)
- Back up your Mac using Time Machine or another backup method before updating
- Open System Settings (or System Preferences on older macOS versions)
- Navigate to General > Software Update
- Wait for macOS to check for available updates
- If an update is available, click Update Now or download and install the update
- Ensure your Mac is connected to power during the installation process
- Restart your Mac when prompted to complete the installation
- After restarting, verify the update by going to Apple menu > About This Mac and confirming the version matches 13.7.7 (Ventura), 14.7.7 (Sonoma), or 15.6 (Sequoia)
