The `Toybox.Graphics.BufferedBitmap.initialize` API method in CIQ API version 2.3.0 through 4.1.7 does not validate its parameters, which can result in integer overflows when allocating the underlying bitmap buffer. A malicious application could call the API method with specially crafted parameters and hijack the execution of the device's firmware. • https://developer.garmin.com/connect-iq/api-docs/Toybox/Graphics/BufferedBitmap.html#initialize-instance_function https://developer.garmin.com/connect-iq/compatible-devices https://github.com/anvilsecure/garmin-ciq-app-research/blob/main/advisories/CVE-2023-23298.md • CWE-190: Integer Overflow or Wraparound •

The `Toybox.Ant.BurstPayload.add` API method in CIQ API version 2.2.0 through 4.1.7 suffers from a type confusion vulnreability, which can result in an out-of-bounds write operation. A malicious application could create a specially crafted `Toybox.Ant.BurstPayload` object, call its `add` method, override arbitrary memory and hijack the execution of the device's firmware. • https://developer.garmin.com/connect-iq/api-docs/Toybox/Ant/BurstPayload.html#add-instance_function https://github.com/anvilsecure/garmin-ciq-app-research/blob/main/advisories/CVE-2023-23306.md • CWE-787: Out-of-bounds Write •

The `news` MonkeyC operation code in CIQ API version 1.0.0 through 4.1.7 fails to check that string resources are not extending past the end of the expected sections. A malicious CIQ application could craft a string that starts near the end of a section, and whose length extends past its end. Upon loading the string, the GarminOS TVM component may read out-of-bounds memory. • https://github.com/anvilsecure/garmin-ciq-app-research/blob/main/advisories/CVE-2023-23301.md • CWE-125: Out-of-bounds Read •

In Garmin Connect 4.61, terminating a LiveTrack session wouldn't prevent the LiveTrack API from continued exposure of private personal information. NOTE: this is disputed by the vendor because the LiveTrack API service is not a customer-controlled product. En Garmin Connect 4.61, finalizar una sesión de LiveTrack no impediría que la API LiveTrack exponga continuamente información personal privada. NOTA: el proveedor cuestiona esto porque el servicio LiveTrack API no es un producto controlado por el cliente. • https://www.samwallace.dev/research/Harvesting%20Emails%20with%20Expired%20Garmin%20LiveTrack%20Sessions • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
