Low: kernel

Issue Overview:

The rio_ioctl function in drivers/net/ethernet/dlink/dl2k.c in the Linux kernel before 3.3.7 does not restrict access to the SIOCSMIIREG command, which allows local users to write data to an Ethernet adapter via an ioctl call.

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.
