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 or EMUI versionGo to Settings > About Phone > Version on the Huawei device and verify the OS version numberAffected if The version is exactly 13.0.0 or 14.0.0 for EMUI, or exactly 3.0.0, 4.0.0, or 4.2.0 for HarmonyOS
-
Confirm screen lock with PIN is enabledNavigate to Settings > Security > Screen Lock on the device and verify that PIN is set as the lock methodAffected if PIN is configured as the screen lock authentication method, making the PIN enhancement module active and potentially vulnerable
-
Check security patch levelGo to Settings > About Phone > Security Patch or Settings > System > Software Update to view the installed security updateAffected if The installed security patch is older than the vendor release that addresses CVE-2024-42038 (patch date not specified in provided data)
The device is affected if it runs EMUI 13.0.0/14.0.0 or HarmonyOS 3.0.0/4.0.0/4.2.0, has PIN screen lock enabled, and lacks the vendor security patch for this vulnerability.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedApply the vendor-specific security patch for this vulnerability through system updates. Users should ensure their devices are running the latest security patch level. For enterprise deployments, inventory affected device models and prioritize patching based on risk.
EMUI 14.0.1 or later; HarmonyOS 4.3.0 or later (specific patch versions available from Huawei)
