  "details": "In the Linux kernel, the following vulnerability has been resolved:  net/rds: reset op_nents when zerocopy page pin fails  When iov_iter_get_pages2() fails in rds_message_zcopy_from_user(), the pinned pages are released with put_page(), and rm-\u003edata.op_mmp_znotifier is cleared.  But we fail to properly clear rm-\u003edata.op_nents.  Later when rds_message_purge() is called from rds_sendmsg() the cleanup loop iterates over the incorrectly non zero number of op_nents and frees them again.  Fix this by properly resetting op_nents when it should be in rds_message_zcopy_from_user().",
