Detailsinfo

A vulnerability, which was classified as critical, has been found in Dialog Semiconductor SDK up to 5.0.4. This issue affects an unknown functionality of the component Bluetooth Low Energy. The manipulation as part of a L2CAP Packet 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. The summary by CVE is:

The Bluetooth Low Energy implementation on Dialog Semiconductor SDK through 5.0.4 for DA14580/1/2/3 devices does not properly restrict the L2CAP payload length, allowing attackers in radio range to cause a buffer overflow via a crafted Link Layer packet.

The weakness was presented 02/10/2020. The identification of this vulnerability is CVE-2019-17517 since 10/12/2019. The attack can only be done within the local network. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available.

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