high Tenable Cloud Security Plugin ID 468950

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: ip6_gre: require CAP_NET_ADMIN in
the device netns for changelink ip6gre_changelink() and ip6erspan_changelink() operate on at most two
netns, dev_net(dev) and the tunnel link netns t->net. They differ once the device is created in or moved
to a netns other than the one the request runs in. The rtnl changelink path checks CAP_NET_ADMIN only
against dev_net(dev), so a caller privileged there but not in t->net can rewrite a tunnel that lives in
t->net. Gate both ops on rtnl_dev_link_net_capable() at their top, before any attribute is parsed.
(CVE-2026-72052)

Solution

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