  "title": "md/raid1,raid10: fix bio accounting for split md cloned bios",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  md/raid1,raid10: fix bio accounting for split md cloned bios  Use md_cloned_bio() to control bio accounting instead of relying on r1bio_existed in raid1 or the io_accounting flag in raid10.  The previous logic does not reliably reflect whether a bio is an md cloned bio. When a failed bio is split and resubmitted via bio_submit_split_bioset() on the error path, this can lead to either double accounting for md cloned bios, or missing accounting for bios returned from bio_submit_split_bioset()  Fix this by using md_cloned_bio() to detect md cloned bios and skip accounting accordingly.",
