No exploit is available.

Detailsinfo

A vulnerability was found in NXP KW41Z up to 2.2.1. It has been rated as critical. Affected by this issue is an unknown code block of the component Bluetooth Low Energy. The manipulation as part of a BLE Link Layer Header leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The Bluetooth Low Energy (BLE) stack implementation on the NXP KW41Z (based on the MCUXpresso SDK with Bluetooth Low Energy Driver 2.2.1 and earlier) does not properly restrict the BLE Link Layer header and executes certain memory contents upon receiving a packet with a Link Layer ID (LLID) equal to zero. This allows attackers within radio range to cause deadlocks, cause anomalous behavior in the BLE state machine, or trigger a buffer overflow via a crafted BLE Link Layer frame.

The weakness was published 02/10/2020. This vulnerability is handled as CVE-2019-17060 since 10/01/2019. Access to the local network is required for this attack. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.

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