Summary
xfrm: xfrm_interface: require CAP_NET_ADMIN in the device netns for changelink
Details

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

xfrm: xfrminterface: require CAPNET_ADMIN in the device netns for changelink

xfrmichangelink() operates on at most two netns, devnet(dev) and the interface link netns xi->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 xi->net can rewrite an interface that lives in xi->net.

Gate xfrmichangelink() on rtnldevlinknet_capable() at its top, before any attribute is parsed.
