CVE-2022-42829
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 use after free issue was addressed with improved memory management. 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 · high confidenceA use-after-free vulnerability in iOS 16.1, iPadOS 16, and macOS Ventura 13 allows an application with root privileges to escalate to kernel-level code execution due to improper memory management.

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 > Version, or connect to a computer with iTunes/Finder and check the device summary. Compare the version number to the affected range (all versions below 16.1).Affected if The installed iOS version is lower than 16.1
-
Check iPadOS version on iPadOn the device, go to Settings > General > About > Version, or connect to a computer with iTunes/Finder and check the device summary. Compare the version number to the affected range (all versions below 16).Affected if The installed iPadOS version is lower than 16
-
Check macOS versionClick the Apple menu in the top-left corner and select About This Mac, or run the command 'sw_vers' in Terminal. The version number displayed is the installed macOS version.Affected if The installed macOS version is lower than 13.0 (Ventura)
The device is affected if it is running any version of iOS prior to 16.1, iPadOS prior to 16, or macOS prior to 13.0, and if an attacker already has root-level access on the device to attempt the privilege escalation.
