CVE-2022-41627
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 physical IoT device of the AliveCor's KardiaMobile, a smartphone-based personal electrocardiogram (EKG) has no encryption for its data-over-sound protocols. Exploiting this vulnerability could allow an attacker to read patient EKG results or create a denial-of-service condition by emitting sounds at similar frequencies as the device, disrupting the smartphone microphone’s ability to accurately read the data. To carry out this attack, the attacker must be close (less than 5 feet) to pick up and emit sound waves.
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 confidenceThe KardiaMobile IoT device transmits EKG data to a smartphone using unencrypted sound waves. An attacker within 5 feet can intercept patient EKG results by receiving the same sound transmissions, or cause denial-of-service by emitting interfering frequencies that disrupt the device-to-smartphone communication.

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.
-
Inventory KardiaMobile devicesSearch your device inventory, procurement records, or conduct a physical walkthrough of clinical areas to identify Alivecor KardiaMobile, KardiaMobile 6l, or KardiaMobile Card handheld EKG devicesAffected if Any of these three device models are present in the environment
-
Verify device is operationalConfirm the device powers on and has been used to capture EKG readings; check usage logs or interview staff who operate the devicesAffected if The device has been used to transmit EKG data to a smartphone application
-
Confirm sound-based transmission methodObserve or document that the device transmits EKG data to a smartphone via audible or ultrasonic sound waves rather than Bluetooth, WiFi, or wired connectionAffected if The device uses sound wave audio transmission to send EKG data to the paired smartphone app
-
Assess physical proximity exposureEvaluate whether devices are used in areas where unauthorized persons could approach within 5 feet during EKG transmissions, such as open wards, waiting areas, or shared examination roomsAffected if EKG transmissions occur in spaces where eavesdropping or frequency interference is physically plausible
If KardiaMobile, KardiaMobile 6l, or KardiaMobile Card devices are present and used to capture EKG data transmitted via sound waves, the environment is affected since all firmware versions lack encryption for the audio-based transmission channel.

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 dataVendor must implement encryption for the sound-based data transmission protocol and deploy firmware updates to devices; users should update firmware when available and use devices in private settings to minimize proximity exposure.
