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 versionGo to Apple menu > About This Mac or run 'sw_vers' in TerminalAffected if The version shows 14.0 (macOS Sonoma initial release) - this is the only affected version
-
Verify Bluetooth access prompts behaviorObserve whether applications prompt for Bluetooth permission when first accessing Bluetooth featuresAffected if On macOS 14.0, applications may access Bluetooth without generating user consent prompts (the vulnerability condition)
You are affected only if your macOS version is exactly 14.0; versions 14.1 and later include the fix and are not vulnerable.

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 · scopedUpdate to macOS Sonoma 14.1 or later to receive the permissions fix. Verify that Bluetooth access prompts appear for applications and review application permissions in System Settings.
macOS Sonoma 14.1 or later
