CVE-2024-44227
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 18 and iPadOS 18, macOS Sequoia 15. An app may be able to cause unexpected system termination or corrupt kernel memory.
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 Apple iOS, iPadOS, and macOS allows a malicious or compromised application to cause system termination or corrupt kernel memory, potentially leading to privilege escalation or system instability.

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 version on iPhoneOn the iPhone, go to Settings > General > About and look at the Version fieldAffected if Version is less than 18.0 (e.g., 17.x)
-
Check iPadOS version on iPadOn the iPad, go to Settings > General > About and look at the Version fieldAffected if Version is less than 18.0 (e.g., 17.x)
-
Check macOS version on MacClick the Apple menu > About This Mac and look at the macOS versionAffected if Version is less than 15.0 (e.g., 14.x or earlier, also known as Sonoma or older)
-
Review installed applications for suspicious appsCheck the device for any unknown, untrusted, or recently installed applications that were not obtained from the official App Store (iOS/iPadOS) or from identified developers (macOS)Affected if A malicious or compromised application is present on the device
The device is affected if it runs iOS/iPadOS version below 18.0 or macOS version below 15.0, AND a malicious application has been installed that could exploit the kernel memory handling flaw.
