CVE-2016-10088

Priority
Low
Description
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.
Ubuntu-Description
It was discovered that the generic SCSI block layer in the Linux kernel did
not properly restrict write operations in certain situations. A local
attacker could use this to cause a denial of service (system crash) or
possibly gain administrative privileges.
