      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mlx5: Fix devx subscribe-event unwind NULL dereference\n\nMLX5_IB_METHOD_DEVX_SUBSCRIBE_EVENT() links event_sub into sub_list\nbefore initializing the fields used by the shared error path.\n\nIf eventfd_ctx_fdget() then fails, the unwind path dereferences\nevent_sub->ev_file in uverbs_uobject_put() and calls\nsubscribe_event_xa_dealloc() with an unset xa_key_level1.\n\nsubscribe_event_xa_alloc() creates the XA entry exactly once for a given\nkey_level1, on the first occurrence of that key. The unwind path must\ntherefore call subscribe_event_xa_dealloc() exactly once for it as well.\n\nEnforce that by adding devx_key_in_sub_list() and calling\nsubscribe_event_xa_dealloc() only when the last matching pending entry is\nbeing cleaned up.",
