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. (NVD)
