Description

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: fix refcount bug in iwpm_get_nlmsg_request() iwpm_get_nlmsg_request() initializes refcount _after_ list_add_tail() making it accessible to global list where another CPU can kref_get() on nlmsg_request causing a refcount "addition on 0" bug. Fix this by initializing kref _before_ list_add_tail() so refcount for nlmsg_request can be incremented/decremented normally. In addition, also initialize every field before list_add_tail().
