Google: sys-kernel/cchost-kernel-6_12, sys-kernel/csql-kernel-6_12, sys-kernel/lakitu-kernel-6_12, sys-kernel/lakitu-nc-kernel-6_12: security update to 19506.448.8

critical Tenable Cloud Security Plugin ID 469810

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: vxlan: use neigh_ha_snapshot() in
route_shortcircuit() The neighbour hardware address n->ha can be updated asynchronously by the neighbour
subsystem, protected by n->ha_lock seqlock. Reading n->ha without holding the seqlock loop can lead to
torn reads or reading a partially updated MAC address. Use neigh_ha_snapshot() in route_shortcircuit() to
safely copy n->ha under read_seqbegin()/read_seqretry() lock protection before using it. Note that
arp_reduce() and neigh_reduce() seem to have the same issue left for future patches. (CVE-2026-74475)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
