CVE-2022-42830
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 memory handling. This issue is fixed in iOS 16.1 and iPadOS 16, macOS Ventura 13. An app with root privileges may be able to execute arbitrary code with kernel 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 privilege escalation vulnerability in Apple operating systems where an application with root privileges can execute arbitrary code with kernel privileges due to improper memory handling. The vulnerability allows escaping user-space sandbox to achieve kernel-level code execution.

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 iPhoneOn the device, go to Settings > General > About, or connect to computer and view in Finder/iTunes. Look for the 'Version' field.Affected if Version is less than 16.1
-
Check iPadOS version on iPadOn the device, go to Settings > General > About, or connect to computer and view in Finder/iTunes. Look for the 'Version' field.Affected if Version is less than 16.0
-
Check macOS versionUse the command 'sw_vers -productVersion' in Terminal, or go to System Settings > About This Mac. The version number will be displayed.Affected if Version is less than 13.0
Your device is affected if it runs any iOS version below 16.1, iPadOS below 16.0, or macOS below 13.0, and has an application with root privileges that could exploit the kernel memory handling flaw.
