CVE-2022-48479
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 · uneditedThe facial recognition TA of some products has the out-of-bounds memory read vulnerability. Successful exploitation of this vulnerability may cause exceptions of the facial recognition service.
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 confidenceOut-of-bounds memory read vulnerability in the facial recognition Trusted Application (TA) of affected products. This memory safety flaw could allow reading beyond allocated buffer boundaries, potentially exposing sensitive data or causing service exceptions.

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 HarmonyOS versionCheck the device or system's HarmonyOS version by going to Settings > About Phone > Version, or use the 'getprop' command via ADB: 'adb shell getprop ro.build.version.release'Affected if The version displayed is exactly 2.0 (HarmonyOS 2.0)
-
Confirm facial recognition is configuredVerify that facial recognition is enabled on the device. On HarmonyOS 2.0 devices, check Settings > Security > Face Recognition, or look for facial recognition enrollment records in the systemAffected if Facial recognition feature has been set up or enabled on the device
-
Locate facial recognition Trusted ApplicationInspect the Trusted Application environment. On HarmonyOS devices, the facial recognition TA typically runs within the Trusted Execution Environment (TEE). Use device diagnostics or TEE logs if available to identify the facial recognition TA componentAffected if The facial recognition TA component is present and running on the device
-
Check TA version or build dateIf accessible, query the facial recognition TA for its version information. This may require elevated access or vendor-specific diagnostic tools. Look for TA binary version metadata in the TEE partitionAffected if The facial recognition TA version matches the vulnerable HarmonyOS 2.0 release
A user is affected if the device runs HarmonyOS 2.0 and has the facial recognition Trusted Application enabled, as this combination exposes the system to the out-of-bounds memory read flaw.

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 dataObtain and apply vendor-provided patches for the facial recognition TA. If no patch is available, isolate affected systems and monitor for anomalous behavior.
