Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: RDMA/iwcm: Fix use-after-free of work
 objects after cm_id destruction The commit 59c68ac31e15 ("iw_cm: free cm_id resources on the last deref")
 simplified cm_id resource management by freeing cm_id once all references to the cm_id were removed. The
 references are removed either upon completion of iw_cm event handlers or when the application destroys the
 cm_id. This commit introduced the use-after-free condition where cm_id_private object could still be in
 use by event handler works during the destruction of cm_id. The commit aee2424246f9 ("RDMA/iwcm: Fix a
 use-after-free related to destroying CM IDs") addressed this use-after- free by flushing all pending works
 at the cm_id destruction. However, still another use-after-free possibility remained. It happens with the
 work objects allocated for each cm_id_priv within alloc_work_entries() during cm_id creation, and
 subsequently freed in dealloc_work_entries() once all references to the cm_id are removed. If the cm_id's
 last reference is decremented in the event handler work, the work object for the work itself gets removed,
 and causes the use- after-free BUG below: BUG: KASAN: slab-use-after-free in

 avoid the use-after-free of cm_id_private work objects, ensure that the last reference to the cm_id is
 decremented not in the event handler works, but in the cm_id destruction context. For that purpose, mo
