CVE-2022-32927
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 15.7.1 and iPadOS 15.7.1, iOS 16.1 and iPadOS 16. Joining a malicious Wi-Fi network may result in a denial-of-service of the Settings app.
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 memory handling vulnerability in iOS and iPadOS allows a malicious Wi-Fi network to trigger a denial-of-service condition in the Settings app. The attacker causes the Settings app to become unresponsive or crash by exploiting improper memory management when the device joins a crafted wireless network.

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 installed iOS or iPadOS versionGo to Settings > General > About on the device and note the version number shown next to 'Version'Affected if The version is below 15.7.1 (for iOS 15.x) or exactly 16.0 (for iOS 16.x)
-
Identify if device has joined untrusted Wi-Fi networksReview the known Wi-Fi networks the device has connected to by checking Settings > Wi-Fi > 'Known Networks' or reviewing saved networksAffected if The device has connected to Wi-Fi networks that are not trusted or are controlled by an unverified party
-
Check Settings app stability after joining new Wi-FiOpen the Settings app and observe if it becomes unresponsive, crashes, or hangs after the device has joined a Wi-Fi networkAffected if The Settings app becomes unresponsive or crashes specifically after joining a crafted wireless network
-
Verify iOS version matches affected rangesConfirm the full version string including build number if visible, and compare against: iPadOS < 15.7.1, iOS < 15.7.1, or iOS = 16.0Affected if The exact version falls within the affected ranges and the device has exposure to untrusted Wi-Fi
The device is affected if it runs iOS/iPadOS version below 15.7.1 (for iOS 15.x) or exactly version 16.0 (for iOS 16.x) and has connected to a potentially malicious Wi-Fi network that could trigger the Settings app crash.

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 · scoped15.7.1
Update affected iOS/iPadOS devices to version 15.7.1 or later (for iOS 15.x) or 16.1 or later (for iOS 16.x). Avoid joining untrusted Wi-Fi networks until devices are patched.
iOS 16.1 or later / iPadOS 16 or later
- Back up your iPhone or iPad using iCloud or Finder/iTunes before starting the update
- Connect your device to power and Wi-Fi
- Go to Settings > General > Software Update
- Download and install iOS 16.1 or later (or iPadOS 16 or later)
- After the update completes, verify the version by checking Settings > General > About
