CVE-2019-8510
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 · uneditedAn out-of-bounds read issue existed that led to the disclosure of kernel memory. This was addressed with improved input validation. This issue is fixed in iOS 12.2, macOS Mojave 10.14.4, tvOS 12.2, watchOS 5.2. A malicious application may be able to determine kernel memory layout.
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 confidenceAn out-of-bounds read vulnerability in Apple operating systems allowed a malicious application to read kernel memory beyond allocated boundaries, potentially disclosing kernel memory layout information useful for exploit development.

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 your Apple operating systemDetermine whether the system is running iOS, macOS, tvOS, or watchOS. On iOS/tvOS/watchOS, go to Settings > General > About. On macOS, go to Apple menu > About This Mac.Affected if The device runs any of the affected Apple operating systems listed in the CVE.
-
Check iOS versionOn iPhone or iPad, go to Settings > General > About and note the version number shown next to 'Version'.Affected if The installed iOS version is lower than 12.2 (for example, 12.1.4 or earlier).
-
Check macOS versionOn Mac, go to Apple menu > About This Mac. The version number appears below the macOS name (for example, 10.14.3).Affected if The installed macOS version is lower than 10.14.4.
-
Check tvOS versionOn Apple TV, go to Settings > General > About and note the version number.Affected if The installed tvOS version is lower than 12.2.
-
Check watchOS versionOn Apple Watch, open the Watch app on paired iPhone, go to General > About, and note the watchOS version.Affected if The installed watchOS version is lower than 5.2.
A system is affected if it is running any of the listed Apple operating systems with a version number lower than the corresponding fixed version (iOS 12.2, macOS 10.14.4, tvOS 12.2, or watchOS 5.2).

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.
From vendor data5.210.14.412.2
Apply the vendor-supplied updates: iOS 12.2+, macOS Mojave 10.14.4+, tvOS 12.2+, or watchOS 5.2+. In enterprise environments, test for application compatibility before deploying broadly.
