CVE-2025-43512
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 logic issue was addressed with improved checks. This issue is fixed in iOS 18.7.3 and iPadOS 18.7.3, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3, macOS Tahoe 26.2. An app may be able to elevate privileges.
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 logic flaw in Apple operating systems allows a malicious application to bypass authorization checks and elevate privileges to higher permission levels. The fix involves improved validation checks within the affected OS components.

-
Identify macOS versionRun 'sw_vers -productVersion' in Terminal to get the installed macOS version number (e.g., 14.6.1 or 15.4)Affected if The version displayed is below 14.8.3, or is 15.0 through 15.7.2 (this includes unpatched macOS Sonoma and Sequoia installations)
Your macOS installation is affected if it is any version of macOS Sonoma before 14.8.3, or macOS Sequoia between 15.0 and 15.7.2 inclusive.

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 · scoped14.8.315.7.3
Apply the vendor-supplied security updates (iOS 18.7.3, iPadOS 18.7.3, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3, or macOS Tahoe 26.2) to all affected devices to remediate the privilege escalation vulnerability.
macOS Sonoma 14.8.3 or macOS Sequoia 15.7.3
- Back up your Mac using Time Machine or another backup solution before applying system updates
- Open System Settings (or System Preferences on older macOS versions)
- Click on 'General' and then select 'Software Update'
- Allow macOS to check for available updates
- If macOS Sonoma (14.x) is installed, locate and install the update to version 14.8.3 or later
- If macOS Sequoia (15.x) is installed, locate and install the update to version 15.7.3 or later
- Restart your Mac when prompted to complete the installation
- After restarting, verify the update was successful by returning to Software Update and confirming the installed version
