CVE-2024-27825
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 downgrade issue affecting Intel-based Mac computers was addressed with additional code-signing restrictions. This issue is fixed in macOS Sonoma 14.5. An app may be able to bypass certain Privacy preferences.
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 code-signing bypass vulnerability in macOS allows applications on Intel-based Macs to bypass Privacy preferences (likely TCC permissions). This is a downgrade issue that circumvents code-signing restrictions, enabling an app to access privacy-protected resources without proper user consent.

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 Mac processor architectureClick Apple menu > About This Mac and look under 'Processor', or run `sysctl -n machdep.cpu.brand_string` in TerminalAffected if The Mac uses an Intel processor (not Apple Silicon) - this vulnerability only affects Intel-based systems
-
Check installed macOS versionClick Apple menu > About This Mac, or run `sw_vers -productVersion` in TerminalAffected if The macOS version is 14.0, 14.1, 14.2, 14.3, or 14.4 (versions 14.5 and later are patched)
-
Verify TCC permission enforcementReview privacy-protected resources accessed by applications in System Settings > Privacy & Security, or inspect the TCC database at /Library/Application Support/com.apple.TCC/TCC.db for unexpected permission grantsAffected if Applications have accessed privacy-protected resources (camera, microphone, contacts, etc.) without user consent prompts, indicating code-signing bypass was exploited
You are affected if you run macOS 14.0-14.4 on an Intel-based Mac and have apps that accessed privacy-protected data without TCC consent prompts.

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 · scoped14.5
Update affected Intel-based Mac systems to macOS Sonoma 14.5 or later to apply the code-signing restriction fixes.
macOS Sonoma 14.5
- Back up your Mac using Time Machine or another backup solution before proceeding with the update
- Navigate to System Settings > General > About to confirm your current macOS version is between 14.0 and 14.4
- Open System Settings > General > Software Update
- Click 'Update Now' or 'Upgrade Now' to download and install macOS Sonoma 14.5
- Follow the on-screen prompts and allow the Mac to restart as required during the installation process
- After the update completes, verify the installation by checking System Settings > General > About shows version 14.5
