"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnvdimm: pmem: keep PREFLUSH before data writes\n\npmem_submit_bio() records a REQ_PREFLUSH error, but continues to copy the\nbio data and can later overwrite the error with a successful REQ_FUA flush.\nThat lets data writes run after a failed preflush and can complete the bio\nsuccessfully despite the failed ordering barrier.\n\nRun the REQ_PREFLUSH flush synchronously before touching the bio data and\ncomplete the bio with the flush error if it fails. Keep asynchronous flush\nchaining for REQ_FUA. At that point, data copy has completed and the parent\nbio can wait for the chained flush bio."
