The sg implementation in the Linux kernel through 4.9 does not properly
restrict write operations in situations where the KERNEL_DS option is set,
which allows local users to read or write to arbitrary kernel memory
locations or cause a denial of service (use-after-free) by leveraging
access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c.
NOTE: this vulnerability exists because of an incomplete fix for
CVE-2016-9576.
