CVE-2026-43234

A flaw was found in the Linux kernel's team driver. A local user can exploit this vulnerability by manipulating network devices and namespaces. Specifically, when a slave device is unregistered from a team interface while a NETDEVCHANGEMTU event is pending, it can lead to a deadlock or resource...

CVE-2026-31692

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...

CVE-2026-31692

In The Linux kernel, CVE-2026-31692 affects the rtnetlink path: the peer namespace CAP_NET_ADMIN check is missing in rtnl_newlink() when creating paired devices (e.g., veth, vxcan, netkit). This enables an unprivileged user with a user namespace to create interfaces in arbitrary network namespace...
