Amazon Linux 2023: CVE-2024-41091: Important priority package update for kernel (Multiple Advisories)

In the Linux kernel, the following vulnerability has been resolved:
tun: add missing verification for short frame
The cited commit missed to check against the validity of the frame length
in the tun_xdp_one() path, which could cause a corrupted skb to be sent
downstack. Even before the skb is transmitted, the
tun_xdp_one-->eth_type_trans() may access the Ethernet header although it
can be less than ETH_HLEN. Once transmitted, this could either cause
out-of-bound access beyond the actual length, or confuse the underlayer
with incorrect or inconsistent header length in the skb metadata.
In the alternative path, tun_get_user() already prohibits short frame which
has the length less than Ethernet header size from being transmitted for
IFF_TAP.
This is to drop any frame shorter than the Ethernet header size just like
how tun_get_user() does.
CVE: 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.
