Descriptions
Linux Linux kernel version at least v4.8 onwards, probably well before contains a Insufficient input validation vulnerability in bnx2x network card driver that can result in DoS: Network card firmware assertion takes card off-line. This attack appear to be exploitable via An attacker on a must pass a very large, specially crafted packet to the bnx2x card. This can be done from an untrusted guest VM..
El kernel de Linux, al menos desde la versión v4.8, contiene una vulnerabilidad de validación de entradas insuficiente en el controlador de la tarjeta de red bnx2x que puede resultar en un DoS: la aserción del firmware de la tarjeta de red toma la tarjeta offline. Parece que el ataque puede ser explotado mediante un atacante que deba pasar un paquete muy grande, especialmente manipulado a la tarjeta bnx2x. Esto puede realizarse desde una máquina virtual invitada no fiable.
Improper validation in the bnx2x network card driver of the Linux kernel version 4.15 can allow for denial of service (DoS) attacks via a packet with a gso_size larger than ~9700 bytes. Untrusted guest VMs can exploit this vulnerability in the host machine, causing a crash in the network card.
