Ledger Bitcoin App 2.1.0 Address Derivation Error via Miniscript
Ledger Bitcoin app versions 2.1.0 and 2.1.1 contain an address derivation vulnerability that allows attackers to cause incorrect Bitcoin addresses to be displayed by exploiting improper handling of miniscript policies containing the a: fragment.

Ledger Nano X, Flex, Stax MCU Firmware Update Denial of Service
Ledger Nano X, Flex, and Stax devices contain a denial of service vulnerability in the MCU firmware update process due to missing validation of the reset_handler parameter during firmware flashing.
