CVE-2022-42820
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 memory corruption issue was addressed with improved state management. This issue is fixed in iOS 16.1 and iPadOS 16, macOS Ventura 13. An app may cause unexpected app termination or arbitrary code execution.
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 confidenceMemory corruption vulnerability in iOS 16.1, iPadOS 16, and macOS Ventura 13 stemming from improper state management. An application can trigger this to cause unexpected app termination or achieve arbitrary code execution with the application's privileges.

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 the device typeDetermine whether the device is an iPhone, iPad, or Mac computer. On iOS/iPadOS, go to Settings > General > About. On macOS, click the Apple menu > About This Mac.Affected if Any Apple device (iPhone, iPad, or Mac) is in use
-
Check iOS version on iPhoneOn iPhone, go to Settings > General > About and note the version number shown next to 'Version'. Compare this against 16.1.Affected if iOS version is lower than 16.1 (for example, 16.0.x or earlier)
-
Check iPadOS version on iPadOn iPad, go to Settings > General > About and note the version number shown next to 'Version'. Compare this against 16.0.Affected if iPadOS version is lower than 16.0 (for example, 15.x.x or earlier)
-
Check macOS version on MacOn Mac, click the Apple menu > About This Mac. Note the version number (such as 12.x for Monterey). Compare this against 13.0.Affected if macOS version is lower than 13.0 (Ventura)
A device is affected if it runs iOS before 16.1, iPadOS before 16.0, or macOS before 13.0 (Ventura).

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.
dbcve · scoped13.016.016.1
Apply Apple security updates (iOS 16.1+, iPadOS 16+, macOS Ventura 13+) to all affected devices. Prioritize devices running unpatched iOS/iPadOS as mobile endpoints present higher exposure risk for malicious app installation.
iOS 16.1+, iPadOS 16.0+, or macOS Ventura 13.0+ (depending on device type)
- Check current iOS/iPadOS version by going to Settings > General > About, or check macOS version by clicking Apple menu > About This Mac
- Back up your device data using iCloud or Finder/iTunes before upgrading
- For iPhone: Upgrade to iOS 16.1 or later via Settings > General > Software Update
- For iPad: Upgrade to iPadOS 16.0 or later via Settings > General > Software Update
- For Mac: Upgrade to macOS Ventura 13.0 or later via System Preferences > Software Update
- Verify the update was successful by re-checking the version number
