Descriptions
In Firecracker 0.20.x before 0.20.1 and 0.21.x before 0.21.2, the network stack can freeze under heavy ingress traffic. This can result in a denial of service on the microVM when it is configured with a single network interface, and an availability problem for the microVM network interface on which the issue is triggered.
En Firecracker versiones 0.20.x anteriores a 0.20.1 y versiones 0.21.x anteriores a 0.21.2, la pila de red puede congelarse bajo tráfico de entrada pesado. Esto puede resultar en una denegación de servicio en el microVM cuando es configurado con una única interfaz de red, y un problema de disponibilidad para la interfaz de red de microVM en la cual el problema es desencadenado
