CVE-2019-8780
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 permissions logic. This issue is fixed in iOS 13.1 and iPadOS 13.1, tvOS 13. 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 confidenceA local malicious application on iOS 13.0, iPadOS 13.0, or tvOS 13 can determine kernel memory layout due to insufficient permissions checks. This information disclosure could aid in developing exploits for other kernel vulnerabilities.

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 > Version and note the version number (e.g., 13.0, 13.0.1, 13.0.2)Affected if The version displayed is below 13.1 (for example, 13.0, 13.0.1, or 13.0.2)
-
Check tvOS version on Apple TVGo to Settings > General > About > Version and note the version numberAffected if The version displayed is below 13.0 (for example, 12.x.x)
-
Confirm device model is an iPhone or iPadGo to Settings > General > About > Model Name to verify the device type. This vulnerability affects iPhone and iPad devices running iOS, not Macs or other Apple devices.Affected if The device is an iPhone or iPad running an affected iOS version
-
Verify no unauthorized or malicious apps are installedReview the installed applications list for any unfamiliar or suspicious apps, particularly those requesting unusual permissions or sideloaded outside the App StoreAffected if A malicious local application is installed on a vulnerable iOS/tvOS version (this is a prerequisite for exploitation)
You are affected if your iPhone or iPad runs iOS below 13.1, or your Apple TV runs tvOS below 13.0, and a malicious local application is present on the device.

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 data13.013.1
Apply vendor patches by updating affected devices to iOS 13.1/iPadOS 13.1/tvOS 13 or later. This is a vendor-patched vulnerability requiring OS updates.
