CVE-2019-17060Public exploit

BLE service deadlock via zero-LLID buffer overwrite

Published Feb 10, 2020 · Updated Aug 5, 2024

Buffer overwrite in BLE stack for NXP KW41Z with Bluetooth Low Energy Driver 2.2.1 and earlier allows physically proximate attackers to deadlock BLE. The receive path accepts an LLID value of zero and overwrites memory adjacent to the packet buffer, leaving the BLE state machine in a malfunctioning deadlock. Exploitation requires radio range and an affected BLE-enabled firmware build; the bounded consequence is interruption of BLE service.
