Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
scsi: pm8001: Fix use-after-free for aborted TMF sas_task<br />
<br />
Currently a use-after-free may occur if a TMF sas_task is aborted before we<br />
handle the IO completion in mpi_ssp_completion(). The abort occurs due to<br />
timeout.<br />
<br />
When the timeout occurs, the SAS_TASK_STATE_ABORTED flag is set and the<br />
sas_task is freed in pm8001_exec_internal_tmf_task().<br />
<br />
However, if the I/O completion occurs later, the I/O completion still<br />
thinks that the sas_task is available. Fix this by clearing the ccb->task<br />
if the TMF times out - the I/O completion handler does nothing if this<br />
pointer is cleared.
