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 macOS Big Sur 11.6.6, macOS Monterey 12.3, Security Update 2022-004 Catalina. A remote user may cause an 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 confidenceA use-after-free vulnerability in macOS allows a remote attacker to execute arbitrary code by exploiting improper memory management. The vulnerability is triggerable through malicious content processed by the affected macOS component, leading to memory corruption that can be weaponized for code execution.

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 macOS versionRun 'sw_vers -productVersion' in Terminal to retrieve the exact macOS version numberAffected if The version is 10.15.7, or falls between 11.0-11.6.5, or between 12.0-12.2.x (any version less than 12.3 on Monterey)
-
Confirm macOS codename and buildRun 'sw_vers' to display the product name (e.g., macOS, Mac OS X) and compare against the affected versionsAffected if The system reports macOS 11.x (Big Sur) or 12.x (Monterey) in the vulnerable version range, or Mac OS X 10.15.7 (Catalina)
-
Verify if security update 2022-004 or later is installedCheck System Preferences > Software Update, or run 'system_profiler SPSoftwareDataType' to list installed updatesAffected if The system shows no security updates installed for Catalina, or is missing Big Sur 11.6.6 or Monterey 12.3 updates
You are affected if your macOS version is exactly 10.15.7, or between 11.0-11.6.5, or between 12.0-12.2.x and you have not applied the corresponding security update.
