What is CVE-2019-17518?

The Bluetooth Low Energy implementation within Dialog Semiconductor's SDK for DA1468x devices, specifically up to version 1.0.14.1081, is susceptible to a buffer overflow condition. This vulnerability arises from the device's failure to properly handle link layer packets with payload lengths that exceed the expected size. Attackers within radio range can exploit this flaw by sending specially crafted packets, potentially leading to unpredictable behavior, including crashes or unauthorized access to affected systems, such as smart locks.
