CVE-2022-50583

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

md/raid0, raid10: Don't set discard sectors for request queue

It should use disk_stack_limits to get a proper max_discard_sectors rather than setting a value by stack drivers.

And there is a bug. If all member disks are rotational devices, raid0/raid10 set max_discard_sectors. So the member devices are not ssd/nvme, but raid0/raid10 export the wrong value. It reports warning messages in function __blkdev_issue_discard when mkfs.xfs like this:
