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 · uneditedThe issue was addressed with improved handling of caches. This issue is fixed in iOS 16.2 and iPadOS 16.2, macOS Ventura 13.1, tvOS 16.2, watchOS 9.2. An app may be able to read sensitive location information.
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 vulnerability in Apple's cache handling mechanisms allowed an application to potentially read sensitive location information that should have been protected. The flaw involved improper access controls on cached location data, enabling unauthorized disclosure of user location through the cache.

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 iPhone or iPadOS versionOn the device, go to Settings > General > About and note the version number listed next to 'Version'Affected if Version is below 16.2 (e.g., 16.1, 16.0, 15.x)
-
Check macOS versionClick the Apple menu > About This Mac. The version number appears below the macOS nameAffected if Version is below 13.1 (e.g., 13.0, 12.x, 11.x)
-
Check tvOS versionOn Apple TV, go to Settings > General > About > VersionAffected if Version is below 16.2 (e.g., 16.1, 16.0, 15.x)
-
Check watchOS versionOn iPhone, open the Watch app, go to General > About, and read the watchOS versionAffected if Version is below 9.2 (e.g., 9.1, 9.0, 8.x)
Any Apple device running an OS version lower than the fixed release (iOS/iPadOS/tvOS 16.2+, macOS 13.1+, watchOS 9.2+) is affected by this cache handling vulnerability that allows unauthorized location data disclosure.
