I would request three commits to be backported to stable/4.14 c75ab8a55ac1 ("net/rds: remove user triggered WARN_ON in rds_sendmsg") 7dba92037baf ("net/rds: Use ERR_PTR for rds_message_alloc_sgs()") bdc2ab5c61a5 ("net/rds: Fix a use after free in rds_message_map_pages")
The commits fix bug where input-parameters to 'rds_message_alloc_sgs()' are just tested with WARN_ON instead of error-return
