In the Linux kernel, the following vulnerability has been resolved:
RDMA/srp: Do not call scsi_done() from srp_abort()
After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler
callback, it performs one of the following actions:
* Call scsi_queue_insert().
* Call scsi_finish_command().
* Call scsi_eh_scmd_add().
Hence, SCSI abort handlers must not call scsi_done(). Otherwise all
the above actions would trigger a use-after-free. Hence remove the
scsi_done() call from srp_abort(). Keep the srp_free_req() call
before returning SUCCESS because we may not see the command again if
SUCCESS is returned.
