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
