CVE-2026-98252

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().
