CVE-2016-10088

Published: 30 December 2016

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.

From the Ubuntu security team

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.

Priority

Low
