PatchTheCVECVE-2019-17517: The Bluetooth Low Energy implementation on Dialog Semiconductor SDK through 5.0.4 for DA14580/1/2/3 devices do
CVE-2019-17517 is a medium-severity flaw (CVSS 5.7) affecting software development kit. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- No elevated risk signals yet
A fixed release or distro patch exists.
