Title
High traffic causes corrupt SPI packets in OpenThread leading to denial of service
Summary
In high traffic environments, a Silicon Labs OpenThread RCP (see impacted versions) fails to clear the SPI transmit buffer and may send a corrupt packet over SPI to its host,  causing the host to reset the RCP which results in a denial of service.
