    Description:

    This update for the Linux Kernel 4.4.21-90 fixes several issues.

    The following security bugs were fixed:
    - CVE-2016-10088: The sg implementation in the Linux kernel did not
    properly restrict write operations in situations where the KERNEL_DS
    option is set, which allowed 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 (bsc#1019079).
