Google: sys-kernel/lakitu-kernel-6_1, sys-kernel/lakitu-kernel-6_6: security update to 18613.75.4

medium Tenable Self-Hosted Container Security Plugin ID 466493

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: net: add more sanity checks to
qdisc_pkt_len_init() One path takes care of SKB_GSO_DODGY, assuming skb->len is bigger than hdr_len.
virtio_net_hdr_to_skb() does not fully dissect TCP headers, it only make sure it is at least 20 bytes. It
is possible for an user to provide a malicious 'GSO' packet, total length of 80 bytes. - 20 bytes of IPv4
header - 60 bytes TCP header - a small gso_size like 8 virtio_net_hdr_to_skb() would declare this packet
as a normal GSO packet, because it would see 40 bytes of payload, bigger than gso_size. We need to make
detect this case to not underflow qdisc_skb_cb(skb)->pkt_len. (CVE-2024-49948)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18613.75.4 or later.
