Silicon Labs Z-Wave Series 500 v6.84.0 was discovered to contain insecure permissions.

An issue in Silicon Labs Z-Wave Series 500 v6.84.0 allows attackers to execute arbitrary code.

Insecure permissions in Silicon Labs (SiLabs) Z-Wave Series 700 and 800 v7.21.1 allow attackers to arbitrarily change the device type in the controller's memory, leading to a Denial of Service (DoS).

Insecure permissions in Silicon Labs (SiLabs) Z-Wave Series 700 and 800 v7.21.1 allow attackers to change the wakeup interval of end devices in controller memory, disrupting the device's communications with the controller.

Insecure permissions in Silicon Labs (SiLabs) Z-Wave Series 700 and 800 v7.21.1 allow attackers to cause disrupt communications between the controller and the device itself via repeatedly sending crafted packets to the controller.

Insecure permissions in Silicon Labs (SiLabs) Z-Wave Series 700 and 800 v7.21.1 allow attackers to cause a Denial of Service (DoS) via repeatedly sending crafted packets to the controller.

Insecure permissions in Silicon Labs (SiLabs) Z-Wave Series 700 and 800 v7.21.1 allow attackers to create a fake node via supplying crafted packets.

Silicon Labs Gecko OS Debug Interface Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Silicon Labs Gecko OS. Authentication is not required to exploit this vulnerability. The specific flaw exists within the debug interface. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer.

Use After Free vulnerability in Silicon Labs Bluetooth SDK on 32 bit, ARM may allow an attacker with precise timing capabilities to intercept a small number of packets intended for a recipient that has left the network.This issue affects Silabs Bluetooth SDK: through 8.0.0.

High traffic environments may result in NULL Pointer Dereference vulnerability in Silicon Labs's Ember ZNet SDK before v7.4.0, causing a system crash.

Due to an allocation of resources without limits, an uncontrolled resource consumption vulnerability exists in Silicon Labs Ember ZNet SDK prior to v7.4.0.0 (delivered as part of Silicon Labs Gecko SDK v4.4.0) which may enable attackers to trigger a bus fault and crash of the device, requiring a reboot in order to rejoin the network.

Ember ZNet between v7.2.0 and v7.4.0 used software AES-CCM instead of integrated hardware cryptographic accelerators, potentially increasing risk of electromagnetic and differential power analysis sidechannel attacks.

Malformed S2 Nonce Get Command Class packets can be sent to crash PC Controller v5.54.0 and earlier.

Malformed Device Reset Locally Command Class packets can be sent to the controller, causing the controller to assume the end device has left the network. After this, frames sent by the end device will not be acknowledged by the controller. This vulnerability exists in PC Controller v5.54.0, and earlier.

TRNG is used before initialization by ECDSA signing driver when exiting EM2/EM3 on Virtual Secure Vault (VSE) devices. This defect may allow Signature Spoofing by Key Recreation.This issue affects Gecko SDK through v4.4.0.

A heap-based buffer overflow vulnerability exists in the HTTP Server functionality of Weston Embedded uC-HTTP git commit 80d4004. A specially crafted network packet can lead to arbitrary code execution. An attacker can send a malicious packet to trigger this vulnerability.

A memory leak in the Silicon Labs' Bluetooth stack for EFR32 products may cause memory to be exhausted when sending notifications to multiple clients, this results in all Bluetooth operations, such as advertising and scanning, to stop.
