Summary

With a specially crafted Python script, an attacker could send continuous startMeasurement commands over an unencrypted Bluetooth connection to the affected device. This would prevent the device from connecting to a clinician's app to take patient readings and ostensibly flood it with requests, resulting in a denial-of-service condition.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
