CVE-2024-45446
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 · uneditedAccess permission verification vulnerability in the camera driver module Impact: Successful exploitation of this vulnerability will affect availability.
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 · low confidenceThis is an access permission verification vulnerability in a camera driver module. The vulnerability allows unauthorized access to camera functionality due to insufficient permission checks, leading to availability impact (likely denial of service or camera unavailability). The medium severity suggests the exploit may require some level of access or complexity.

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 device EMUI versionGo to Settings > About Phone > Version on the Huawei device and verify the EMUI build number matches 12.0.0, 13.0.0, or 14.0.0Affected if The EMUI version is exactly 12.0.0, 13.0.0, or 14.0.0
-
Check device HarmonyOS versionGo to Settings > About Phone > Version on the Huawei device and verify the HarmonyOS version matches 2.0.0, 2.1.0, 3.0.0, 3.1.0, 4.0.0, or 4.2.0Affected if The HarmonyOS version is exactly 2.0.0, 2.1.0, 3.0.0, 3.1.0, 4.0.0, or 4.2.0
-
Verify camera driver module is presentCheck if the camera application is installed and functional on the device - attempt to open the camera app or check system app list for camera-related packagesAffected if Camera driver module exists on the device (required for the vulnerability to be applicable)
The device is affected if it runs EMUI 12.0.0, 13.0.0, and 14.0.0 or HarmonyOS 2.0.0 through 4.2.0 and contains the vulnerable camera driver module.

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-provided patches for the camera driver module. If no patch is available, restrict access to camera functions through proper authorization controls and validate all permission checks in the camera driver code.
