The Bluetooth Low Energy implementation on Microchip Technology BluSDK Smart through 6.2 for ATSAMB11 devices does not properly restrict link-layer data length on reception, allowing attackers in radio range to cause a denial of service (crash) via a crafted packet.

On Microchip RN4870 devices, when more than one consecutive PairReqNoInputNoOutput request is received, the device becomes incapable of completing the pairing process. A third party can inject a second PairReqNoInputNoOutput request just after a real one, causing the pair request to be blocked.
