Физический уровень - это нижний уровень стека протоколов BLE, который определяет основные радиочастотные параметры связи BLE, включая частоту сигнала, схему модуляции и т.д.Рабочая частота BLE составляет 2,4 ГГц. Он использует частотную модуляцию GFSK и использует механизм…
A vulnerability exists in the firmware of embedded BLE radios that are part of some Aruba Access points. An attacker who is able to exploit the vulnerability could install new, potentially malicious firmware into the AP's BLE radio and could then gain access to the AP's console port. This vulnerability is applicable only if the BLE radio has been enabled in affected access points. The BLE radio is disabled by default. Note - Aruba products are NOT affected by a similar vulnerability being tracked as…
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.
The Bluetooth Low Energy (BLE) stack implementation on Cypress PSoC 4 through 3.62 devices 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.
