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...

CVE-2026-72053

The CVE-2026-72053 entry describes a Linux kernel vulnerability in the ipip driver related to changelink in ipip_changelink(). The issue arises because CAP_NET_ADMIN is checked only against the device’s netns (dev_net(dev)) while a tunnel can reside in a different netns (t->net), allowing a pr...
