Details

In the Linux kernel, the following vulnerability has been resolved:

scsi: pm8001: Fix use-after-free for aborted TMF sas_task

Currently a use-after-free may occur if a TMF sastask is aborted before we handle the IO completion in mpissp_completion(). The abort occurs due to timeout.

When the timeout occurs, the SASTASKSTATEABORTED flag is set and the sastask is freed in pm8001execinternaltmftask().

However, if the I/O completion occurs later, the I/O completion still thinks that the sas_task is available. Fix this by clearing the ccb->task if the TMF times out - the I/O completion handler does nothing if this pointer is cleared.
