CVE-2025-68371

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 sdev_destroy(), 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 controllers SCSI device list before running; if not, the reset is skipped.

• Cancel any pending TMF work that has not started in sdev_destroy().

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