In the Linux kernel, the following vulnerability has been resolved:
s390/qeth: Check CAP_NET_ADMIN for private ioctls
Gate the SIOCDEVPRIVATE ioctl commands SIOC_QETH_ADP_SET_SNMP_CONTROL, SIOC_QETH_GET_CARD_TYPE and SIOC_QETH_QUERY_OAT with CAP_NET_ADMIN capable check to ensure unprivileged users cannot invoke them.
