A vulnerability was found in NXP SDK up to 2.2.1. It has been classified as critical. Affected is an unknown part of the component Bluetooth Low Energy. The manipulation as part of a Crafted Packet 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 confidentiality, integrity, and availability. CVE summarizes:

The Bluetooth Low Energy implementation on NXP SDK through 2.2.1 for KW41Z devices does not properly restrict the Link Layer payload length, allowing attackers in radio range to cause a buffer overflow via a crafted packet.

The weakness was published 02/12/2020. This vulnerability is traded as CVE-2019-17519 since 10/12/2019. Local access is required to approach this attack. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
