CVE-2024-32991
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 · uneditedPermission verification vulnerability in the wpa_supplicant 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 · moderate confidenceThis is a permission verification vulnerability in the wpa_supplicant module, which handles Wi-Fi authentication on Linux/Unix systems. The flaw allows unauthorized access or actions due to missing or incorrect permission checks, leading to availability impact (likely denial of service).
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 operating systemCheck if the system is running Huawei Emui or HarmonyOS by examining system properties, /etc/os-release (if available), or device information settingsAffected if The system is running Huawei Emui 12.0.0, 13.0.0, or 14.0.0; or HarmonyOS 2.0.0, 2.1.0, 3.0.0, 3.1.0, 4.0.0, or 4.2.0
-
Locate wpa_supplicant componentSearch for the wpa_supplicant binary or service on the system using commands like 'which wpa_supplicant', 'find /system -name wpa_supplicant*', or checking running processes for wpa_supplicantAffected if wpa_supplicant is present and running on the device
-
Verify Wi-Fi functionality is enabledCheck if Wi-Fi is turned on and if the wpa_supplicant service is actively handling Wi-Fi authentication. This can be done by examining active network services, Wi-Fi settings, or process lists related to wirelessAffected if Wi-Fi is enabled and wpa_supplicant is actively managing Wi-Fi connections
-
Confirm permission configurationExamine the wpa_supplicant configuration file (commonly wpa_supplicant.conf) and its file permissions. Look for any misconfigurations that could allow unauthorized access to the Wi-Fi management interfaceAffected if The wpa_supplicant configuration has weak permissions or allows unauthenticated interface access
The user is affected if their device runs one of the listed Huawei Emui or HarmonyOS versions AND has wpa_supplicant enabled with a vulnerable permission 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.
From vendor dataApply vendor patches for wpa_supplicant immediately; until then, restrict network access and limit exposure of the wpa_supplicant interface to trusted users.
