Loading vulnerability…
CVE-2024-26846 is a race condition in the Linux kernel NVMe over Fibre Channel host driver module-exit path. During nvme-fc module removal, controller-deletion work can race with cleanup of leftover identifier allocations. Synchronization intended to prevent double freeing did not cover all execution paths, allowing the exit path to wait indefinitely for completion. The upstream fix eliminates the unnecessary ID-destruction cleanup, relies on controller-deletion cleanup to release IDs, and flushes the nvme_delete_wq workqueue before nvme_fc_exit_module returns.

Linux kernel NVMe-over-Fibre-Channel module-unload flaw.
A Linux kernel NVMe over Fibre Channel module-unload handling flaw.
A low-severity Linux kernel NVMe Fibre Channel (nvme-fc) module-unload vulnerability, resolved to prevent waiting indefinitely when the module is unloaded.
A Linux kernel NVMe over Fibre Channel (nvme-fc) race-condition vulnerability during module unload. Improper synchronization can leave the unload path waiting indefinitely, producing a local denial of service through system/module instability or a persistent hang.
