Summary
In the Linux kernel, the following vulnerability has been resolved: geneve: require CAP_NET_ADMIN in the device netns for changelink A tunnel changelink() operates on at most two netns, dev_net(dev) and the sticky underlay netns geneve->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 geneve->net can rewrite a geneve device whose underlay lives in geneve->net. geneve_changelink() applies the new configuration against geneve->net: geneve_link_config() and the geneve_quiesce()/geneve_unquiesce() pair reopen the underlay sockets in that netns (geneve_sock_add() uses geneve->net), so the same reasoning as the tunnel changelink series applies here. Gate geneve_changelink() with rtnl_dev_link_net_capable(), at the top of the op before any attribute is parsed, matching ipgre_changelink() and the rest of the "require CAP_NET_ADMIN in the device netns for changelink" series.

Once a geneve device exists with geneve-\u003enet differing from dev_net(dev) (via IFLA_NET_NS_FD migration or IFLA_LINK_NETNSID newlink), a single deterministic netlink changelink bypasses the missing check with no race or memory-layout dependency.\\nPR:L - The rtnl entry path requires CAP_NET_ADMIN in dev_net(dev), obtainable by an unprivileged local user inside a user+network namespace via unshare --user --map-root-user --net; no CAP_NET_ADMIN in the sticky underlay netns geneve-\u003enet is needed.\\nUI:N - The attack is fully programmatic through netlink from the attacker\u0027s own process; no victim action such as mounting a filesystem, opening a file, or clicking is required.\\nS:C - geneve_changelink applies geneve_link_config() and geneve_quiesce()/geneve_unquiesce() (reopening underlay sockets via geneve_sock_add() in geneve-\u003enet) while authorization is checked only against dev_net(dev), crossing into another tenant\u0027s or the host\u0027s network namespace.\\nC:H - An attacker can set IFLA_GENEVE_REMOTE/REMOTE6 to redirect encapsulated overlay traffic to an attacker-controlled endpoint and read tunneled payloads from the victim underlay netns.\\nI:H - Unauthorized changelink mutates live tunnel remote endpoint, TTL/TOS/DF/label, and MTU in geneve-\u003enet, enabling redirection and injection of overlay traffic without authorization in that namespace.\\nA:H -
