      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ip6_tunnel: require CAP_NET_ADMIN in the device netns for changelink\n\nip6_tnl_changelink() operates on at most two netns, dev_net(dev) and the\ntunnel link netns t->net. They differ once the device is created in or\nmoved to a netns other than the one the request runs in. The rtnl\nchangelink path checks CAP_NET_ADMIN only against dev_net(dev), so a\ncaller privileged there but not in t->net can rewrite a tunnel that\nlives in t->net.\n\nGate ip6_tnl_changelink() on rtnl_dev_link_net_capable() at its top,\nbefore any attribute is parsed.",
