+Subject: [PATCH] scsi: mptsas: dequeue request object in case of an error
+
+Fix CVE-2021-3392
+
+While processing SCSI i/o requests in mptsas_process_scsi_io_request(),
+the Megaraid emulator appends new MPTSASRequest object 'req' to
+the 's->pending' queue. In case of an error, this same object gets
+dequeued in mptsas_free_request() only if SCSIRequest object
+'req->sreq' is initialised. This may lead to a use-after-free issue.
+Unconditionally dequeue 'req' object from 's->pending' to avoid it.
+
+Fixes: CVE-2021-3392
