DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the copy_desc_to_mbuf() function when processing Vhost header. A remote guest can send a packet with the Vhost header crossing more than two descriptors and force application to allocate all available mbufs, causing a denial of service condition for the other guest running on the hypervisor.
Update the affected package dpdk to the latest version.
