[ovs-dev] [PATCH] conntrack.c: Add missing return value check to prevent nptr dereference.

Function ovs_ct_limit_cmd_get() defined in net/openvswitch/conntrack.c may cause a null pointer dereference as it calls nla_nest_start which may return NULL. The returned value is used in function nla_nest_end() later where the pointer is dereferenced. --- net/openvswitch/conntrack.c | 4
