Nordic Semiconductor, Microchip Technology NRF5340-DK DT100112 was discovered to contain an issue which allows attackers to cause a Denial of Service (DoS) via a crafted ConReq packet.

In Nordic nRF5 SDK for Mesh 5.0, a heap overflow vulnerability can be triggered by sending a series of segmented packets with SegO > SegN

In Nordic nRF5 SDK for Mesh 5.0, a heap overflow vulnerability can be triggered by sending a series of segmented control packets and access packets with the same SeqAuth

Nordic Semiconductor nRF52840 devices through 2020-10-19 have improper protection against physical side channels. The flash read-out protection (APPROTECT) can be bypassed by injecting a fault during the boot phase.

The elliptic curve cryptography (ECC) hardware accelerator, part of the ARM® TrustZone® CryptoCell 310, contained in the NordicSemiconductor nRF52840 through 2021-03-29 has a non-constant time ECDSA implemenation. This allows an adversary to recover the private ECC key used during an ECDSA operation.

Nordic Semiconductor Android BLE Library through 2.2.1 and DFU Library through 1.10.4 for Android (as used by nRF Connect and other applications) can engage in unencrypted communication while showing the user that the communication is purportedly encrypted. The problem is in bond creation (e.g., internalCreateBond in BleManagerHandler).
