  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ntun: add missing verification for short frame\nThe cited commit missed to check against the validity of the frame length\nin the tun_xdp_one() path, which could cause a corrupted skb to be sent\ndownstack. Even before the skb is transmitted, the\ntun_xdp_one-->eth_type_trans() may access the Ethernet header although it\ncan be less than ETH_HLEN. Once transmitted, this could either cause\nout-of-bound access beyond the actual length, or confuse the underlayer\nwith incorrect or inconsistent header length in the skb metadata.\nIn the alternative path, tun_get_user() already prohibits short frame which\nhas the length less than Ethernet header size from being transmitted for\nIFF_TAP.\nThis is to drop any frame shorter than the Ethernet header size just like\nhow tun_get_user() does.\nCVE: CVE-2024-41091", "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." ],
