CVE-2019-17061: Cypress Psoc 4 Ble

Medium severity, CVSS 6.5. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Cypress Psoc 4 Ble: up to and including 3.62
