Google: sys-kernel/csql-kernel-6_1, sys-kernel/lakitu-kernel-6_1: security update to 18203.0.0

medium Tenable Self-Hosted Container Security Plugin ID 450627

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: netfilter: bridge: replace physindev
with physinif in nf_bridge_info An skb can be added to a neigh->arp_queue while waiting for an arp reply.
Where original skb's skb->dev can be different to neigh's neigh->dev. For instance in case of bridging
dnated skb from one veth to another, the skb would be added to a neigh->arp_queue of the bridge. As
skb->dev can be reset back to nf_bridge->physindev and used, and as there is no explicit mechanism that
prevents this physindev from been freed under us (for instance neigh_flush_dev doesn't cleanup skbs from
different device's neigh queue) we can crash on e.g. this stack: arp_process neigh_update skb =
__skb_dequeue(&neigh->arp_queue) neigh_resolve_output(..., skb) ... br_nf_dev_xmit
br_nf_pre_routing_finish_bridge_slow skb->dev = nf_bridge->physindev br_handle_frame_finish Let's use
plain ifindex instead of net_device link. To peek into the original net_device we will use
dev_get_by_index_rcu(). Thus either we get device and are safe to use it or we don't get it and drop skb.
(CVE-2024-35839)
