CVE-2024-27829
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 macOS Sonoma 14.5. Processing a file may lead to 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 memory handling vulnerability in macOS Sonoma allows arbitrary code execution or app termination when processing a specially crafted file. The vulnerability stems from improper memory handling during file processing operations.

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 or go to Apple menu > About This Mac > System Report > Software > System VersionAffected if Version is 14.0, 14.1, 14.2, 14.3, or 14.4 (any version >= 14.0 and < 14.5)
-
Confirm macOS name and buildRun 'uname -a' and check that the kernel is Darwin and the system is macOS Sonoma (14.x)Affected if System is macOS Sonoma 14.0-14.4.x range
-
Identify exposed file processing servicesReview running services that accept file input: check System Settings > Privacy & Security > Extensions, or run 'launchctl list' to see active daemonsAffected if Any application or service that processes files from external or untrusted sources is enabled and running
-
Check for crash logs related to file handlingExamine Console app for recent crashes in /var/log/DiagnosticMessages or ~/Library/Logs, looking for unexpected app terminations during file operationsAffected if Recent crashes occurred in file processing components with no known cause
The system is affected if it runs macOS Sonoma version 14.0 through 14.4.x and processes files from potentially untrusted sources.
