      "title": "net: qrtr: restrict socket creation to the initial network namespace",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: qrtr: restrict socket creation to the initial network namespace\n\nQRTR keeps its entire port and node state in module-global variables\nthat are not partitioned per network namespace: qrtr_local_nid is a\nsingle global node id (always 1) and qrtr_ports is a single global\nxarray. qrtr_port_lookup() and qrtr_local_enqueue() operate on that\nglobal state with no network-namespace check, and qrtr_create() places\nno restriction on the namespace a socket is created in.\n\nAs a result an unprivileged process that creates an AF_QIPCRTR socket\nin a separate network namespace, e.g. via\nunshare(CLONE_NEWUSER | CLONE_NEWNET), can send QRTR datagrams -\nincluding control-plane messages such as QRTR_TYPE_NEW_SERVER - to QRTR\nsockets owned by another namespace, and vice versa. The receiving\nsocket sees such a message as coming from node id 1, indistinguishable\nfrom a legitimate local client, breaking the isolation that network\nnamespaces are expected to provide.\n\nQRTR is a transport to global hardware endpoints (the modem and other\nremote processors) and has no per-namespace semantics; its in-kernel\nname service already creates its socket in init_net only. Confine the\nsocket family to the initial network namespace, as other\nnon-namespace-aware socket families do (see llc_ui_create() and the\nieee802154 socket code).",
