CVE-2022-42793
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 issue in code signature validation was addressed with improved checks. This issue is fixed in macOS Big Sur 11.7, macOS Ventura 13, iOS 16, iOS 15.7 and iPadOS 15.7, macOS Monterey 12.6. An app may be able to bypass code signing checks.
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 confidenceThis is a code signing bypass vulnerability in Apple's macOS and iOS platforms. An application could potentially circumvent code signature validation checks, which are designed to verify the integrity and authenticity of executable code. This allows potentially malicious or tampered code to run without detection by the system's security mechanisms.

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 operating systemDetermine if the system is running macOS or iOS/iPadOS. On macOS, check System Preferences > About or run 'sw_vers'. On iOS/iPadOS, check Settings > General > About.Affected if System is not applicable (this CVE only affects macOS and iOS/iPadOS)
-
Check macOS version on Apple desktops/laptopsRun 'sw_vers -productVersion' in Terminal or open System Preferences > About to view the macOS version number.Affected if Version is 11.0 through 11.6.x, or 12.0 through 12.5.x (vulnerable ranges)
-
Check iOS/iPadOS version on Apple mobile devicesOpen Settings > General > About and note the version number, or connect to a computer and use iTunes/Finder to check the iOS version.Affected if Version is 15.0 through 15.6.x (vulnerable range)
-
Verify the code signing subsystem is activeThis vulnerability exploits the code signing validation mechanism. On affected versions, the code signing bypass applies to any application attempting to run unsigned or tampered code. No specific configuration check needed - the vulnerability exists in the code signing validation logic itself.Affected if Running any application on a vulnerable OS version could potentially bypass code signature checks
A system is affected if it is running macOS 11.0-11.6.x or 12.0-12.5.x, or iOS/iPadOS 15.0-15.6.x - versions prior to the 15.7/11.7/12.6 security updates.
