CVE-2025-68371: scsi: smartpqi: Fix device resources accessed after device removal

Published Dec 24, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved:

scsi: smartpqi: Fix device resources accessed after device removal

Correct possible race conditions during device removal.

Previously, a scheduled work item to reset a LUN could still execute after the device was removed, leading to use-after-free and other resource access issues.

This race condition occurs because the abort handler may schedule a LUN reset concurrently with device removal via sdevdestroy(), leading to use-after-free and improper access to freed resources.

- Check in the device reset handler if the device is still present in the controller's SCSI device list before running; if not, the reset is skipped.

- Cancel any pending TMF work that has not started in sdevdestroy().

- Ensure device freeing in sdevdestroy() is done while holding the LUN reset mutex to avoid races with ongoing resets.

  61. Compensating control

    In the Linux kernel scsi: smartpqi driver, cancel any pending TMF work that has not started in sdev_destroy(); in the device reset handler, verify the device is still present in the controller's SCSI device list before running and skip the reset if it is absent; and free the device in sdev_destroy() while holding the LUN reset mutex to prevent races with ongoing resets and use-after-free.
