Descriptions
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.
En entornos de alto tráfico, Silicon Labs OpenThread RCP (ver versiones afectadas) no logra borrar el búfer de transmisión SPI y puede enviar un paquete corrupto a través de SPI a su host, lo que hace que el host restablezca el RCP y esto resulte en una denegación de servicio.
