CVE-2025-68218

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nvme-multipath: fix lockdep WARN due to partition scan work<br /> <br /> Blktests test cases nvme/014, 057 and 058 fail occasionally due to a<br /> lockdep WARN. As reported in the Closes tag URL, the WARN indicates that<br /> a deadlock can happen due to the dependency among disk-&gt;open_mutex,<br /> kblockd workqueue completion and partition_scan_work completion.<br /> <br /> To avoid the lockdep WARN and the potential deadlock, cut the dependency<br /> by running the partition_scan_work not by kblockd workqueue but by<br /> nvme_wq.
