      "title": "netfs: Fix cancellation of a DIO and single read subrequests",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetfs: Fix cancellation of a DIO and single read subrequests\n\nWhen the preparation of a new subrequest for a read fails, if the\nsubrequest has already been added to the stream->subrequests list, it can't\nsimply be put and abandoned as the collector may see it.  Also, if it\nhasn't been queued yet, it has two outstanding refs that both need to be\nput.  Both DIO read and single-read dispatch fail at this; further, both\ndiffer in the order they do things to the way buffered read works.\n\nFix cancellation of both DIO-read and single-read subrequests that failed\npreparation by the following steps:\n\n (1) Harmonise all three reads (buffered, dio, single) to queue the subreq\n     before prepping it.\n\n (2) Make all three call netfs_queue_read() to do the queuing.\n\n (3) Set NETFS_RREQ_ALL_QUEUED independently of the queuing as we don't\n     know the length of the subreq at this point.\n\n (4) In all cases, set the error and NETFS_SREQ_FAILED flag on the subreq\n     and then call netfs_read_subreq_terminated() to deal with it.  This\n     will pass responsibility off to the collector for dealing with it.",
