Routine

MEDIUM 6.5UPGRADE

CVE-2019-17061 is a medium-severity flaw (CVSS 6.5) affecting psoc 4 ble. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The Bluetooth Low Energy (BLE) stack implementation on Cypress PSoC 4 through 3.62 devices 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.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.
