CVE-2026-74373 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libperf package and not the libperf package as distributed by Centos.
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.
