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.

Uninitialized IV in Silicon Labs SE FW v2.0.0 through v 2.2.1 for internally stored data

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

Zigbee Unauthenticated DoS via NWK Sequence number manipulation

Prior to v7.4.0, Ember ZNet is vulnerable to a denial of service attack through manipulation of the NWK sequence number

Unvalidated input in Silicon Labs PSA Attestation service leads to secure memory access from non-secure memory

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.

Uninitialized variable in Gecko Bootloader can leak secure stack

Uninitialized buffer in GBL parser in Silicon Labs GSDK v4.3.0 and earlier allows attacker to leak data from Secure stack via malformed GBL file.

Bluetooth LE segmented 'prepare write response' packet may lead to out-of-bounds memory access

Forcing the Bluetooth LE stack to segment 'prepare write response' packets can lead to an out-of-bounds memory access.

A heap-based buffer overflow vulnerability exists in the HTTP Server functionality of Weston Embedded uC-HTTP v3.01.01. A specially crafted set of network packets can lead to arbitrary code execution. An attacker can send a malicious packet to trigger this vulnerability.

An out-of-bounds write vulnerability exists in the HTTP Server functionality of Weston Embedded uC-HTTP v3.01.01. A specially crafted network packet can lead to memory corruption. An attacker can send a network request to trigger this vulnerability.
