Description: A vulnerability in SiLabs Z/IP Gateway 7.18.01 and earlier allows an unauthenticated attacker within Z-Wave range to overflow a stack buffer, leading to arbitrary code execution.

A logic error in SiLabs Z/IP Gateway SDK 7.18.02 and earlier allows authentication to be bypassed, remote administration of Z-Wave controllers, and S0/S2 encryption keys to be recovered.

Multiple buffer overflow vulnerabilities in SiLabs Z/IP Gateway SDK version 7.18.01 and earlier allow an attacker with invasive physical access to a Z-Wave controller device to overwrite global memory and potentially execute arbitrary code.

A vulnerability in SiLabs Z/IP Gateway 7.18.01 and earlier allows an authenticated attacker within Z-Wave range to manipulate an array pointer to disclose the contents of global memory.

The initialization vector (IV) used by the secure engine (SE) for encrypting data stored in the SE flash memory is uninitialized.

A memory leak in the EFR32 Bluetooth LE stack 5.1.0 through 5.1.1 allows an attacker to send an invalid pairing message and cause future legitimate connection attempts to fail. A reset of the device immediately clears the error.

Buffer overflow in Wi-Fi Commissioning MicriumOS example in Silicon Labs Gecko SDK v4.2.3 or earlier allows connected device to write payload onto the stack.

Buffer overflow in Platform CLI component in Silicon Labs Gecko SDK v4.2.1 and earlier allows user to overwrite limited structures on the heap.

Compiler removal of buffer clearing in sli_se_driver_mac_compute in Silicon Labs Gecko Platform SDK v4.2.1 and earlier results in key material duplication to RAM.

Compiler removal of buffer clearing in sli_se_sign_hash in Silicon Labs Gecko Platform SDK v4.2.1 and earlier results in key material duplication to RAM.
