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 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.

A vulnerability in the Cisco Discovery Protocol implementation for the Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated, adjacent attacker to execute code remotely or cause a reload of an affected IP Camera. The vulnerability is due to missing checks when processing Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to the targeted IP Camera. A successful exploit could allow the attacker to expose the affected IP Camera for remote code execution or cause it to reload unexpectedly, resulting in a denial of service (DoS) condition. Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). This vulnerability is fixed in Video Surveillance 8000 Series IP Camera Firmware Release 1.0.7 and later.

A vulnerability in the Cisco Discovery Protocol implementation for the Cisco IP Phone could allow an unauthenticated, adjacent attacker to remotely execute code with root privileges or cause a reload of an affected IP phone. The vulnerability is due to missing checks when processing Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to the targeted IP phone. A successful exploit could allow the attacker to remotely execute code with root privileges or cause a reload of an affected IP phone, resulting in a denial of service (DoS) condition. Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).

A vulnerability in the Cisco Discovery Protocol implementation for Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a reload on an affected device. The vulnerability exists because the Cisco Discovery Protocol parser does not properly validate input for certain fields in a Cisco Discovery Protocol message. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. An successful exploit could allow the attacker to cause a stack overflow, which could allow the attacker to execute arbitrary code with administrative privileges on an affected device. Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).

A vulnerability in the Cisco Discovery Protocol implementation for Cisco FXOS Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to a missing check when the affected software processes Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. A successful exploit could allow the attacker to exhaust system memory, causing the device to reload. Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).

An issue was discovered on Swell Kit Mod devices that use the Vandy Vape platform. An attacker may be able to trigger an unintended temperature in the victim's mouth and throat via Bluetooth Low Energy (BLE) packets that specify large power or voltage values.

An exploitable authentication bypass vulnerability exists in the Bluetooth Low Energy (BLE) authentication module of YI M1 Mirrorless Camera V3.2-cn. An attacker can send a set of BLE commands to trigger this vulnerability, resulting in sensitive data leakage (e.g., personal photos). An attacker can also control the camera to record or take a picture after bypassing authentication.

The Bluetooth Low Energy (BLE) subsystem on Tapplock devices before 2018-06-12 allows replay attacks.

The Bluetooth Low Energy (BLE) subsystem on Tapplock devices before 2018-06-12 relies on Key1 and SerialNo for unlock operations; however, these are derived from the MAC address, which is broadcasted by the device.
