CVE-2024-56444
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 · uneditedCross-process screen stack vulnerability in the UIExtension module Impact: Successful exploitation of this vulnerability may affect service confidentiality.
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 cross-process vulnerability in the UIExtension module's screen stack implementation, where improper isolation between processes allows unauthorized access to screen content. A CVSS 7.5 with confidentiality impact suggests the vulnerability enables one process to read or capture display data belonging to another process, likely due to missing access controls in the screen stack management.

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 HarmonyOS versionVerify the installed HarmonyOS version by checking system settings or using 'getprop' command for 'ro.build.version.release' or similar system propertyAffected if The version is exactly 5.0.0 (other versions are not affected)
-
Identify UIExtension module usageCheck if the UIExtension module is active on the device by examining running processes or system services related to UIExtensionAffected if UIExtension module is loaded and running
-
Verify screen stack feature is enabledInspect system configuration or app permissions related to screen stack management in UIExtension - look for any multi-process display sharing configurationsAffected if Cross-process screen stacking or display sharing is enabled between different applications
-
Review inter-process communication permissionsExamine the access control settings for the UIExtension screen stack - check if there are any permissive IPC configurations that allow cross-process screen data accessAffected if Screen stack lacks proper access controls between processes or allows unauthorized inter-process screen content access
A system is affected only if it runs HarmonyOS exactly version 5.0.0 with the UIExtension module active and cross-process screen stack functionality enabled without proper isolation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patches for UIExtension module once available; ensure process isolation boundaries are properly enforced in screen stack handling and implement proper access controls between processes.
