Summary
In the Linux kernel, the following vulnerability has been resolved: dm raid: fix address sanitizer warning in raid_resume There is a KASAN warning in raid_resume when running the lvm test lvconvert-raid.sh. The reason for the warning is that mddev->raid_disks is greater than rs->raid_disks, so the loop touches one entry beyond the allocated length.
