  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ntap: add missing verification for short frame\nThe cited commit missed to check against the validity of the frame length\nin the tap_get_user_xdp() path, which could cause a corrupted skb to be\nsent downstack. Even before the skb is transmitted, the\ntap_get_user_xdp()-->skb_set_network_header() may assume the size is more\nthan ETH_HLEN. Once transmitted, this could either cause out-of-bound\naccess beyond the actual length, or confuse the underlayer with incorrect\nor inconsistent header length in the skb metadata.\nIn the alternative path, tap_get_user() already prohibits short frame which\nhas the length less than Ethernet header size from being transmitted.\nThis is to drop any frame shorter than the Ethernet header size just like\nhow tap_get_user() does.\nCVE: CVE-2024-41090", "A denial of service (DoS) attack was found in the mlx5 driver in the Linux kernel. A KVM guest VM using virtio-net can crash the host by sending a short packet, for example, size < ETH_HLEN. The packet may traverse through vhost-net, macvtap, and vlan without any validation or drop. When this packet is presented to the mlx5 driver on the host side, the kernel panic happens since mlx5_core assumes the frame size is always >= ETH_HLEN." ],
