Descriptions
The netlink_sendmsg function in net/netlink/af_netlink.c in the Linux kernel before 3.5.5 does not validate the dst_pid field, which allows local users to have an unspecified impact by spoofing Netlink messages.
La función netlink_sendmsg en net/netlink/af_netlink.c en el kernel de Linux en versiones anteriores a 3.5.5 no valida el campo dst_pid, lo que permite a usuarios locales tener un impacto no especificado suplantando mensajes Netlink.
