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 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.
Prior to v7.4.0, Ember ZNet is vulnerable to a denial of service attack through manipulation of the NWK sequence number
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
Glitch detection is not enabled by default for the CortexM33 core in Silicon Labs secure vault high parts EFx32xG2xB, except EFR32xG21B.
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.
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.
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.
An integer overflow in Silicon Labs Gecko Bootloader version 4.3.1 and earlier allows unbounded memory access when reading from or writing to storage slots.
Forcing the Bluetooth LE stack to segment 'prepare write response' packets can lead to an out-of-bounds memory access.
The initialization vector (IV) used by the secure engine (SE) for encrypting data stored in the SE flash memory is uninitialized.
An invalid ‘prepare write request’ command can cause the Bluetooth LE stack to run out of memory and fail to be able to handle subsequent connection requests, resulting in a denial-of-service.
