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.
