CVE-2026-64569

In CVE-2026-64569, on Linux kernel builds with CONFIG_INET=n, mpls_valid_fib_dump_req() dereferences NULL when handling RTM_GETROUTE dumps for AF_MPLS because tb[RTA_OIF] is passed to nla_get_u32() without checking presence, and the path bypasses ip_valid_fib_dump_req(). This can allow an unprivi...

kernel: rtnetlink: add missing netlink_ns_capable() check for peer netns

A flaw was found in the Linux kernel's rtnetlink component. An unprivileged local user, leveraging a user namespace, can exploit a missing CAPNETADMIN capability check in the rtnlnewlink function. This allows the user to create paired network devices in arbitrary network namespaces, including the...
