CVE-2025-68218 Details
Description
In the Linux kernel, the following vulnerability has been resolved: nvme-multipath: fix lockdep WARN due to partition scan work Blktests test cases nvme/014, 057 and 058 fail occasionally due to a lockdep WARN. As reported in the Closes tag URL, the WARN indicates that a deadlock can happen due to the dependency among disk->open_mutex, kblockd workqueue completion and partition_scan_work completion. To avoid the lockdep WARN and the potential deadlock, cut the dependency by running the partition_scan_work not by kblockd workqueue but by nvme_wq.
A vulnerability in the Linux kernel's NVMe multipath handling can lead to a deadlock scenario. This issue arises from the way partition scanning is managed, creating a dependency that can cause conflicts in the workqueue processing. The problem has been observed in the Linux kernel stable tree, affecting various versions.
The vulnerability has been addressed by modifying the NVMe multipath code to manage partition scanning through the NVMe workqueue, rather than the default block device workqueue. Users should update to the latest version of the Linux kernel stable tree where this fix has been applied.
