CVE-2024-41090: tap: add missing verification for short frame

First published: Mon Jul 22 2024(Updated: )

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 (i.e. size &lt; ETH_HLEN). The packet may traverse through vhost-net, macvtap and vlan without any validation/drop. When this packet is presented to mlx5 driver on the host side, the kernel panic happens, since mlx5_core assumes the frame size is always &gt;= ETH_HLEN. This vulnerability affects both drivers/net/tun.c and drivers/net/tap.c. <a href="https://access.redhat.com/security/cve/CVE-2024-41090">CVE-2024-41090</a> has been assigned to the TAP side of the issue.
