CVE-2019-8565
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 race condition was addressed with additional validation. This issue is fixed in iOS 12.2, macOS Mojave 10.14.4. A malicious application may be able to gain root 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 race condition in Apple operating systems allowed a malicious local application to escalate privileges to root by exploiting a timing window in validation logic. The vulnerability was patched in iOS 12.2 and macOS Mojave 10.14.4 through additional validation checks that close the race condition window.

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 iOS version on iPhone or iPadGo to Settings > General > About and look at the Version field, or run 'nsregedit' or use Apple Configurator, or check via MDM/enterprise management toolsAffected if Version number is below 12.2 (for example, 12.1.x, 12.0.x, or any earlier version)
-
Check macOS version on Mac computersClick the Apple menu > About This Mac, or run 'sw_vers' in Terminal, or check via enterprise inventory toolsAffected if Version number is below 10.14.4 (for example, 10.14.3, 10.14.2, or any earlier macOS version)
-
Confirm the device is not receiving security updatesCheck if the device can still receive Apple security updates - older devices may be on an unsupported iOS version that will never reach 12.2Affected if The device runs an older iOS major version that Apple no longer supports with patches
A system is affected if it runs iOS before 12.2 or macOS before 10.14.4, as these versions contain the race condition vulnerability that allows local privilege escalation to root.

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 data10.14.412.2
Apply the vendor patches (iOS 12.2+ or macOS Mojave 10.14.4+) to all affected devices. Since this requires local code execution, ensure applications are only installed from trusted sources and consider endpoint protection solutions.
