| CVE-2023-51393 | HIGH7.5 | 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 rejo | 23/02/2024 |
| CVE-2023-51392 | CRITICAL9.8 | 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. | 23/02/2024 |
| CVE-2023-6640 | MEDIUM6.5 | Malformed S2 Nonce Get Command Class packets can be sent to crash PC Controller v5.54.0 and earlier. | 21/02/2024 |
| CVE-2023-6533 | MEDIUM6.5 | 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. | 21/02/2024 |
| CVE-2024-22473 | HIGH7.5 | 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. | 21/02/2024 |
| CVE-2023-45318 | CRITICAL9.8 | 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. | 20/02/2024 |
| CVE-2024-0240 | MEDIUM6.5 | 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. | 15/02/2024 |
| CVE-2023-6874 | HIGH7.5 | Prior to v7.4.0, Ember ZNet is vulnerable to a denial of service attack through manipulation of the NWK sequence number | 05/02/2024 |
| CVE-2023-6387 | HIGH7.5 | A potential buffer overflow exists in the Bluetooth LE HCI CPC sample application in the Gecko SDK which may result in a denial of service or remote code execution | 02/02/2024 |
| CVE-2023-5138 | MEDIUM6.8 | Glitch detection is not enabled by default for the CortexM33 core in Silicon Labs secure vault high parts EFx32xG2xB, except EFR32xG21B. | 03/01/2024 |
| CVE-2023-4280 | CRITICAL9.8 | An unvalidated input in Silicon Labs TrustZone implementation in v4.3.x and earlier of the Gecko SDK allows an attacker to access the trusted region of memory from the untrusted region. | 02/01/2024 |
| CVE-2023-41097 | HIGH7.5 | An Observable Timing Discrepancy, Covert Timing Channel vulnerability in Silabs GSDK on ARM potentially allows Padding Oracle Crypto Attack on CBC PKCS7.This issue affects GSDK: through 4.4.0. | 21/12/2023 |
| CVE-2023-4020 | CRITICAL9.1 | An unvalidated input in a library function responsible for communicating between secure and non-secure memory in Silicon Labs TrustZone implementation allows reading/writing of memory in the secure region of memory from the non-secure region of memory. | 15/12/2023 |
| CVE-2023-5310 | MEDIUM6.5 | A denial of service vulnerability exists in all Silicon Labs Z-Wave controller and endpoint devices running Z-Wave SDK v7.20.3 (Gecko SDK v4.3.3) and earlier. This attack can be carried out only by devices on the network sending a stream of packets to the device. | 15/12/2023 |
| CVE-2023-4489 | CRITICAL9.8 | The first S0 encryption key is generated with an uninitialized PRNG in Z/IP Gateway products running Silicon Labs Z/IP Gateway SDK v7.18.3 and earlier.
