Summary
net: ip_vti: require CAP_NET_ADMIN in the device netns for changelink
Details

In the Linux kernel, the following vulnerability has been resolved:

net: ipvti: require CAPNET_ADMIN in the device netns for changelink

vtichangelink() operates on at most two netns, devnet(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 CAPNETADMIN 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 vtichangelink() on rtnldevlinknet_capable() at its top, before any attribute is parsed.
