NXP MCUXpresso SDK Integer Overflow or Wraparound

The Bluetooth Low Energy implementation on NXP SDK through 2.2.1 for KW41Z devices does not properly restrict the Link Layer payload length, allowing attackers in radio range to cause a buffer overflow via a crafted packet.

NXP MCUXpresso SDK v2.7.0 was discovered to contain a buffer overflow in the function USB_HostProcessCallback().

NXP MCUXpresso SDK v2.7.0 was discovered to contain a buffer overflow in the function USB_HostParseDeviceConfigurationDescriptor().

The Bluetooth Low Energy (BLE) stack implementation on the NXP KW41Z (based on the MCUXpresso SDK with Bluetooth Low Energy Driver 2.2.1 and earlier) 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.
