Loading vulnerability…
CVE-2024-26846 is a race condition in the Linux kernel NVMe over Fibre Channel host driver during nvme-fc module teardown. Concurrent controller deletion and cleanup of leftover IDs can leave the module-exit path waiting indefinitely because its completion handling does not cover all execution paths. The condition causes an indefinite hang while unloading the nvme-fc module. The upstream correction eliminates unnecessary ID destruction, relies on controller-deletion cleanup to release IDs, and flushes the controller-deletion workqueue before module exit returns.
