Description (CNA)
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 controller's 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.
