Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
scsi: smartpqi: Fix device resources accessed after device removal<br />
<br />
Correct possible race conditions during device removal.<br />
<br />
Previously, a scheduled work item to reset a LUN could still execute<br />
after the device was removed, leading to use-after-free and other<br />
resource access issues.<br />
<br />
This race condition occurs because the abort handler may schedule a LUN<br />
reset concurrently with device removal via sdev_destroy(), leading to<br />
use-after-free and improper access to freed resources.<br />
<br />
- Check in the device reset handler if the device is still present in<br />
the controller&#39;s SCSI device list before running; if not, the reset<br />
is skipped.<br />
<br />
- Cancel any pending TMF work that has not started in sdev_destroy().<br />
<br />
- Ensure device freeing in sdev_destroy() is done while holding the<br />
LUN reset mutex to avoid races with ongoing resets.
