CVE-2026-72053 Detail

Description

In the Linux kernel, the following vulnerability has been resolved: net: ipip: require CAP_NET_ADMIN in the device netns for changelink ipip_changelink() operates 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 ipip_changelink() on rtnl_dev_link_net_capable() at its top, before any attribute is parsed.
