What is CVE-2022-50583?

A bug in the Linux kernel's handling of RAID0 and RAID10 configurations can result in incorrect reporting of max_discard_sectors when member disks are rotational devices. The issue arises because the RAID configurations use a hardcoded value instead of correctly utilizing the disk_stack_limits function. This can lead to warning messages during operations such as file system creation, indicating potential data integrity risks and incorrect disk operations. Proper disk stack limits are essential for managing SSD and NVMe drives effectively, making this oversight critical in environments utilizing advanced storage solutions.
