In the Linux kernel, the following vulnerability has been resolved:
scsi: pm8001: Fix use-after-free for aborted SSP/STP sas_task
Currently a use-after-free may occur if a sas_task is aborted by the upper
layer before we handle the I/O completion in mpi_ssp_completion() or
mpi_sata_completion().
In this case, the following are the two steps in handling those I/O
completions:
- Call complete() to inform the upper layer handler of completion of
the I/O.
- Release driver resources associated with the sas_task in
pm8001_ccb_task_free() call.
When complete() is called, the upper layer may free the sas_task. As such,
we should not touch the associated sas_task afterwards, but we do so in the
pm8001_ccb_task_free() call.
Fix by swapping the complete() and pm8001_ccb_task_free() calls ordering.
