In the Linux kernel, the following vulnerability has been resolved: dm raid: fix accesses beyond end of raid member array On dm-raid table load (using raid_ctr), dm-raid allocates an array rs->devs[rs->raid_disks] for the raid device members. rs->raid_disks is defined by the number of raid metadata and image tupples passed into the target's constructor. In the case of RAID layout changes being requested, that number can be different from the current number of members for existing raid sets as defined in their superblocks. Example RAID layout changes include: - raid1 legs being added/removed - raid4/5/6/10 number of stripes changed (stripe reshaping) - takeover to higher raid level (e.g. raid5 -> raid6) When accessing array members, rs->raid_disks must be used in control loops instead of the potentially larger value in rs->md.raid_disks. Otherwise it will cause memory access beyond the end of the rs->devs array. Fix this by changing code that is prone to out-of-bounds access. Also fi...
