  "description": "In the Linux kernel, the following vulnerability has been resolved:  netfs: Fix oops in write-retry from mis-resetting the subreq iterator  Fix the resetting of the subrequest iterator in netfs_retry_write_stream() to use the iterator-reset function as the iterator may have been shortened by a previous retry.  In such a case, the amount of data to be written by the subrequest is not \u0022subreq-\u003Elen\u0022 but \u0022subreq-\u003Elen - subreq-\u003Etransferred\u0022.
