CVE-2023-41295
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 · uneditedVulnerability of improper permission management in the displayengine module. Successful exploitation of this vulnerability may cause the screen to turn dim.
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 an improper permission management vulnerability in the displayengine module, likely on an Android or embedded system. The vulnerability allows unauthorized modification of display settings, specifically causing the screen to dim unexpectedly. Successful exploitation does not require user interaction and can be triggered remotely.

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.
-
Identify the installed Huawei EMUI or HarmonyOS versionOn the device, go to Settings > About Phone > Version, or use 'getprop ro.build.version.emui' or 'getprop ro.build.version鸿蒙' via ADB shell to retrieve the exact OS version numberAffected if The version is exactly 13.0.0 (EMUI) or exactly 3.0.0 or 4.0.0 (HarmonyOS)
-
Confirm the displayengine module is presentCheck for the displayengine system module or service by examining /system/bin/ or /system/lib/ for displayengine components, or review system logs for displayengine activity using 'logcat | grep -i displayengine'Affected if The displayengine module is found and loaded on the device
-
Test for unauthorized display brightness modificationUse a non-privileged app or ADB command (such as adjusting brightness via content provider without holding SYSTEM_ALERT_WINDOW or brightness permission) to attempt changing display brightness outside of authorized system appsAffected if Brightness can be modified by an app that does not hold elevated system privileges or proper displayengine permissions
-
Verify if screen dimming occurs without user interactionMonitor device screen brightness behavior during normal operation or use automated testing to trigger display state changes remotely, observing if unexpected dimming occurs without user-initiated actionAffected if Screen dims unexpectedly without any user input or authorized system trigger
A device is affected if it runs EMUI 13.0.0 or HarmonyOS 3.0.0/4.0.0 and contains the vulnerable displayengine module that allows unauthorized brightness modification leading to unexpected screen dimming.

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 the vendor-supplied patch for CVE-2023-41295 which implements proper permission validation in the displayengine module before allowing display brightness adjustments. Verify that display settings can only be modified by authorized system components.
