Detailsinfo

A vulnerability was found in Cypress PSoC 4 up to 3.61. It has been classified as problematic. This affects an unknown function of the component Bluetooth Low Energy. The manipulation with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on availability. The summary by CVE is:

The Bluetooth Low Energy implementation in Cypress PSoC 4 BLE component 3.61 and earlier processes data channel frames with a payload length larger than the configured link layer maximum RX payload size, which allows attackers (in radio range) to cause a denial of service (crash) via a crafted BLE Link Layer frame.

The weakness was published 02/12/2020. This vulnerability is uniquely identified as CVE-2019-16336 since 09/15/2019. The exploitability is told to be easy.
