CVE-2024-27812
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 logic issue was addressed with improved file handling. This issue is fixed in visionOS 1.2. Processing web content may lead to a denial-of-service.
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 logic error in visionOS file handling during web content processing allows specially crafted web content to trigger a denial-of-service condition. The vulnerability stems from improper validation or handling of files received through web content, causing the system to become unresponsive or unavailable when processing malicious web content.

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 visionOS versionNavigate to Settings > Privacy & Security > About on the Vision Pro device, or use the device management console to retrieve the visionOS build versionAffected if The installed visionOS version is earlier than 1.2 (such as 1.0, 1.1, or any beta/developer preview before 1.2)
-
Identify web content processing applicationsReview installed applications on the visionOS device for web browsers, web views, or applications that render or process web content. Check for Safari, third-party browsers, or any app with embedded web content capabilitiesAffected if Web browsers, web views, or applications that process web content are installed and have been used on the device
The environment is affected if visionOS version is below 1.2 and web content processing applications have been used to access web content.
Generated from the published advisory. Verify against your own configuration.
