Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
nvdimm: pmem: keep PREFLUSH before data writes<br />
<br />
pmem_submit_bio() records a REQ_PREFLUSH error, but continues to copy the<br />
bio data and can later overwrite the error with a successful REQ_FUA flush.<br />
That lets data writes run after a failed preflush and can complete the bio<br />
successfully despite the failed ordering barrier.<br />
<br />
Run the REQ_PREFLUSH flush synchronously before touching the bio data and<br />
complete the bio with the flush error if it fails. Keep asynchronous flush<br />
chaining for REQ_FUA. At that point, data copy has completed and the parent<br />
bio can wait for the chained flush bio.
