Medium: kernel

Issue Overview:

The sg implementation in the Linux kernel did 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.

Affected Packages:

kernel

Issue Correction:
Run yum update kernel to update your system. You will need to reboot your system in order for the new kernel to be running.
