kernel: sg_write function lacks an sg_remove_request call in a certain failure case

A vulnerability was found in sgwrite in drivers/scsi/sg.c in the SCSI generic sg driver subsystem. This flaw allows an attacker with local access and special user or root privileges to cause a denial of service if the allocated list is not cleaned with an invalid Sgfd sfp pointer at the time of...
