CVE-2025-68218

CVE-2025-68218 : Linux kernel vulnerability in the nvme-multipath path. The deadlock risk arises from dependency among disk_open_mutex, kblockd workqueue, and partition_scan_work. The fix cuts the dependency by executing partition_scan_work through the nvme_workqueue (nvme_wq) instead of the kblo...
