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...

kernel: NULL pointer dereference in af_netlink.c:__netlink_ns_capable() allows for denial of service

The Linux kernel was found to be vulnerable to a NULL pointer dereference bug in the netlinknscapable function in the net/netlink/afnetlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service...
