CVE-2022-42805
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 · uneditedAn integer overflow was addressed with improved input validation. This issue is fixed in iOS 15.6 and iPadOS 15.6, macOS Monterey 12.5. An app 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 confidenceInteger overflow in kernel allows a malicious app to escalate privileges to kernel level and execute arbitrary code. This is a local privilege escalation vulnerability requiring an attacker to first run code on the target device.

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 or iPadOS version on Apple mobile devicesOpen Settings > General > About and locate the 'Version' field. Record the full version number (e.g., 15.5).Affected if The version number is less than 15.6 (for example, 15.5, 15.4, 15.3, etc.).
-
Check macOS version on Apple computersOpen System Preferences (or System Settings on newer macOS) > About, or run 'sw_vers -productVersion' in Terminal. Record the version number (e.g., 12.4).Affected if The version is 12.0.0 through 12.4.x (any version starting with 12.0, 12.1, 12.2, 12.3, or 12.4). Versions 12.5 and later are not affected.
-
Confirm the device type matches affected product linesIdentify whether the device is an iPhone (iOS), iPad (iPadOS), or Mac (macOS). This determines which version range applies.Affected if The device runs iOS or iPadOS below 15.6, or macOS between 12.0.0 and 12.4.x.
A user is affected if their device runs iOS or iPadOS version lower than 15.6, or macOS Monterey version 12.0.0 through 12.4.x.

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.

Apply vendor-supplied patches by updating affected devices to iOS 15.6+, iPadOS 15.6+, or macOS Monterey 12.5+.
iOS 15.6, iPadOS 15.6, macOS Monterey 12.5
- For iOS/iPadOS devices: Open Settings app, tap General, tap Software Update, and install iOS 15.6 or iPadOS 15.6
- For macOS devices: Open System Preferences (System Settings on newer macOS), click Software Update, and install macOS Monterey 12.5
- After updating, verify the update was successful by checking Settings > General > About (iOS/iPadOS) or System Preferences > About (macOS) to confirm the version number
