kernel: ip6_gre: Use cached t->net in ip6erspan_changelink()

A flaw was found in the Linux kernel's ip6gre module. An unprivileged user could exploit this vulnerability by migrating a network device, causing the ip6erspanchangelink function to incorrectly handle network namespace references. This error leads to a use-after-free condition when the original...

CVE-2026-72052

The CVE-2026-72052 issue affects the Linux kernel's IP6GRE/IP6ERSPAN changelink logic. Specifically, ip6gre_changelink() and ip6erspan_changelink() could be manipulated if a caller is privileged in dev_net(dev) but not in the tunnel’s netns (t->net). The vulnerability arises because the rtnl c...
